TK3051C Differential Pressure Transmitter

Anhui Tiankang TK3051C Differential Pressure Transmitter Overview

The Anhui Tiankang TK3051C differential pressure transmitter is used to measure the pressure difference between two process points. It is one of the most widely used field instruments in industrial process measurement because one DP transmitter can support several different applications, including differential pressure, flow, liquid level, filter monitoring, and process pressure difference measurement.

In a typical installation, the high-pressure side and low-pressure side are connected to the transmitter through impulse lines, manifolds, flange adapters, or remote diaphragm seals. The transmitter senses the differential pressure and converts it into a 4–20 mA DC signal, which can be sent to a PLC, DCS, recorder, or other control system.

The Anhui Tiankang TK3051C selection table separates different transmitter types, including differential pressure, gauge pressure, absolute pressure, remote seal, and level transmitter configurations. For this page, the focus is the TK3051C differential pressure transmitter configuration used for standard DP, flow, level, and filter pressure drop applications.

4–20 mA HART DP Transmitter Output and Communication

The Anhui Tiankang TK3051C smart differential pressure transmitter can be selected with different output and communication options according to the automation system.

For most industrial projects, 4–20 mA with HART communication is the most practical configuration. It allows the transmitter to provide a continuous analog signal while supporting remote configuration, diagnostics, range setting, and loop checking through a HART communicator or host system.

Key Features of the Anhui Tiankang TK3051C Smart Differential Pressure Transmitter

Flexible Differential Pressure Range Selection

The TK3051C DP transmitter can be selected with different range codes according to the required measuring span. This allows the transmitter to cover low differential pressure applications as well as higher differential pressure process conditions.

For correct selection, the calibrated span should be based on actual process conditions, not only the maximum available sensor range. This is especially important for orifice flow measurement, tank level measurement, and filter differential pressure monitoring.

Suitable for Flow, Level, and DP Measurement

The Anhui Tiankang TK3051C differential pressure transmitter can be used in several process measurement loops:

• Flow measurement with orifice plates, venturi tubes, flow nozzles, pitot tubes, or other DP primary elements.
• Liquid level measurement by measuring hydrostatic pressure difference.
• Filter differential pressure monitoring across filters, strainers, membranes, bag filters, or dust collectors.
• Process pressure difference measurement across pumps, heat exchangers, pipelines, and process equipment.

Multiple Process Connection Options

According to the TK3051C selection structure, process connection and installation options can be selected according to site requirements. A DP transmitter is commonly connected through:

• process flange connection
• 1/4 NPT or 1/2 NPT adapter connection
• impulse tubing and fittings
• 3-valve manifold or 5-valve manifold
• remote diaphragm seal system for difficult media

For most standard differential pressure applications, a 3-valve manifold or 5-valve manifold is recommended to allow isolation, equalization, venting, and calibration.

Diaphragm Material Options

The Anhui Tiankang TK3051C selection table provides multiple diaphragm and wetted material choices. Common options include stainless steel and corrosion-resistant materials.

Actual material selection should be confirmed according to medium composition, concentration, temperature, pressure, and corrosion behaviour.

Filling Fluid Options

The TK3051C series can be selected with different filling fluids according to process temperature, medium compatibility, and application requirements.

Common filling fluid options include:

• silicone oil for general applications
• fluorinated oil for oxygen or special applications
• high-temperature filling fluid for hot process conditions
• low-temperature filling fluid for cold service

For oxygen, chlorine, strong oxidising media, or high/low temperature service, filling fluid selection should be checked carefully before ordering.

Local LCD Display and Configuration

The transmitter can be supplied with an LCD display for local reading and configuration. Depending on configuration, the display can show process value, output current, percentage of range, and related transmitter parameters.

Mounting Bracket and Installation Accessories

The Anhui Tiankang TK3051C DP transmitter can be installed with mounting brackets for pipe mounting, wall mounting, or panel installation. This is especially useful when the transmitter is installed together with a manifold and impulse lines.

Differential Pressure Transmitter Applications for Anhui Tiankang TK3051C

Flow Measurement with DP Primary Elements

The Anhui Tiankang TK3051C DP transmitter can be used with primary flow elements such as orifice plates, venturi tubes, flow nozzles, and pitot tubes. The transmitter measures the differential pressure generated by the primary element, and the control system calculates the corresponding flow rate.

Tank and Vessel Level Measurement

For level measurement, the TK3051C can measure the hydrostatic pressure difference generated by liquid height. It can be used in open tanks, closed tanks, and pressurised vessels depending on installation method and compensation requirements.

For corrosive, viscous, crystallising, or high-temperature media, a remote seal configuration may be required.

Filter Differential Pressure Monitoring

The transmitter can monitor pressure drop across filters, strainers, membranes, bag filters, and dust collectors. A rising differential pressure usually indicates clogging, fouling, or the need for maintenance.

Pump and Pipeline Pressure Difference

The TK3051C can be used to monitor pressure difference across pumps, heat exchangers, valves, and pipelines. This helps evaluate equipment performance and process pressure loss.

Steam, Gas, and Liquid DP Measurement

The transmitter is suitable for liquid, gas, and steam DP applications. For steam service, impulse lines and condensate pots should be installed correctly to protect the transmitter and ensure measurement stability.

How to Select an Anhui Tiankang TK3051C Differential Pressure Transmitter

When selecting an Anhui Tiankang TK3051C differential pressure transmitter, confirm the following details:

1. Measurement purpose
   Confirm whether the transmitter will be used for DP, flow, level, filter monitoring, or process pressure difference.
2. Differential pressure range
   Confirm normal DP, maximum DP, and required calibrated span.
3. Static pressure
   Confirm maximum line pressure on both high-pressure and low-pressure sides.
4. Process medium
   Confirm whether the medium is liquid, gas, steam, corrosive chemical, dirty fluid, viscous medium, or crystallising medium.
5. Process temperature
   For high-temperature steam or hot liquids, confirm whether impulse lines, condensate pots, cooling elements, or remote diaphragm seals are needed.
6. Diaphragm material
   Select 316L, Hastelloy, tantalum, Monel, gold-plated, PTFE-coated, or other options according to medium compatibility.
7. Filling fluid
   Select suitable filling fluid according to temperature, oxygen service, medium compatibility, and response requirement.
8. Output signal
   Confirm whether the project requires 4–20 mA, 4–20 mA + HART, PROFIBUS PA, or FF communication.
9. Installation accessories
   Confirm whether a 3-valve manifold, 5-valve manifold, mounting bracket, impulse tubing, fittings, or remote seal system is required.
10. Certification and documentation
    Confirm whether explosion-proof certification, inspection documents, test reports, or project-specific documentation are required.

Anhui Tiankang TK3051C DP Transmitter vs Remote Seal DP Transmitter

For clean media and standard process conditions, the standard TK3051C DP transmitter is usually more economical. For crystallising, viscous, corrosive, or high-temperature media, a remote seal DP transmitter should be considered.
