High Temperature Pressure Transmitter

Brand: Xi'an UTOP Measurement Instrument Co, Ltd

UMPB Series Melt Pressure Transmitters are developed from strain gauge technology. The UMPB are constructed with a full bridge strain gauge circuit and 100% made from stainless steel material.

In addition, the pressure diaphragm features a surface treatment with special alloy coating for all the UMPB models.

Both the rigid stem and flexible extension provide thermal isolation to UMPT’s electronic circuitry, which enable UMPB suitable for melt pressure and melt temperature measurements.

UMPB-a Melt Pressure Transmitter can work with digital pressure meters, so as to realize the measurement & control for pressure.

With internal 80% FSO shunt calibration, UMPB-a’s zero and span is adjustable, and its amplified output signal can be inputted to PLC directly.

Because of its features of high accuracy of pressure measurement, this product is widely poplar in oversea and home market.

UMPB-b Melt Pressure Transmitter is manufactured by using a temperature sensor based on UMPB-a, suitable for melt pressure and temperature measurement. Its performance is same as UMPB-a.

UMPB-c Melt Pressure Transmitter is manufactured by using flexible extension based on UMPB-b, providing further thermal isolation for electronic circuitry. Its performance is same as UMPB-a.

UMPB-d Melt Pressure Transmitter is manufactured by using a temperature sensor based on UMPB c, suitable for melt pressure and melt temperature measurements. Its performance is same as UMPB-c.

UMPB Series Melt Pressure Transmitters are widely used for melt pressure measurement and control in chemical fiber equipment, plastic and rubber manufacturing equipment, medicine equipment, food processing equipment etc.
