Jcmc Multivariable Transmitter With Hart - China

consists of a differential pressure sensor module with integrated electronic adapter unit, an amplifier module with a control unit and a two-wire system RTD input terminal to measure process temperature

The transmitter adopts modularized design.

It consists of a differential pressure sensor module with integrated electronic adapter unit, an amplifier module with a control unit and a two-wire system RTD input terminal to measure process temperature.

The sensor module adopts full-welded structure, interior of which is a twin-barrel system with an intact overload isolation diaphragm, and one absolute pressure sensor and one differential pressure sensor are installed inside.

The absolute pressure sensor is only installed on the high-pressure side, and the measured pressure will be taken as reference value, in order to compensate influence from static pressure.

The differential pressure sensor is made up of one capillary tube connected with negative pole of the sensor module.

An additional differential pressure (Dp) will be applied onto diaphragm of the differential pressure sensor through the isolation diaphragm and filler liquid.

Check for tiny variation of the diaphragm, which shall result in changes of output voltage of the testing system.

The voltage signal direct proportional to the input pressure will be digitalized through the adapter before being transmitted into the amplifier, and then the amplifier will perform linearization on the signal as well as temperature compensation.

Then, three values of Dp, P and T can be converted signals direct proportional to mass flowrate through compensation.

Except for mass flowrate (Qm), Dp, P, T and Qv can also make for other purpose of application.

According to differences of transmitter models, connection between the transmitter and process can be fulfilled through female screw on elliptic flange on the transmitter, or connection between remote flanges and process pipelines or flanges.

The transmitter adopts a two-wire system, the same pair of leads in which can be used to connect working voltage, signal outputs (4～20mA) and digital quantities.

Electrical connection can be fulfilled through interconnection with terminals through cable inlet.
