Product Description

  4~20mA DC Accurate Analog Water Tank Liquids Stable Differential Pressure Transmitter (MDM490)

Features:

    (1)    Full stainless steel construction, compact size, easy installation;
    (2)    Laser welding, full-sealed construction; Protection IP65;
    (3)    Using piezoresistive differential pressure sensor, 316L isolated diaphragm;
    (4)    Temperature compensation and aging, stable performance;
    (5)    Zero and span adjustable outside;
    (6)   Ex-proof version MDM490 conforms to GB3836.4 standard; Ex-proof certificate is approved;
    (7)   CCS, CE and ROHS certificates

Description:
MDM490 differential pressure transmitter uses piezoresistive differential pressure sensor as sensing element. Silicon oil is filled in between die and two diaphragms, when measured differential pressure is added on two diaphragm, the pressure could be transferred onto die through silicon oil.

Sensor die connects with amplifier circuit through wires, using semi-conductor's piezoresistive effect, transforming differential pressure signal into electric signal. The whole differential pressure tranmitter is used for differential pressure measurement of petroleum, chemi-industry, power station and hydrology, etc.
