Selection Support Before Quotation

Pressure measurement products are not selected only by appearance or product name. Two instruments may look similar, but the suitable configuration can be different because of the process medium, temperature, pressure range, diaphragm material, connection standard, installation position or communication requirement.SIY Electric can help review working conditions, check existing model numbers, compare replacement options and prepare a suitable configuration before quotation. This is especially useful for differential pressure, diaphragm seal, remote seal, flange-mounted, sanitary and customized pressure measurement applications.
