Overview
YJ-G-L/H/T/S single flange differential pressure/pressure transmitter is used to measure the presence of
Solid and precipitating liquids, as well as steam and other media. Its membrane box is used to prevent media
Directly entering the pressure sensor component of the differential pressure transmitter, causing the transmitter to measure
Inaccurate measurement or direct damage to the sensor, using silicon between it and the transmitter
Oil and other filling fluids transmit pressure.
YJ-G-L/H/T/S single flange differential pressure/pressure transmitter for measuring liquids
The liquid level of a body, gas, or vapor. Density, pressure, and flow rate, and then
It is converted into a 4-20mADC HART current signal output. Can be used with HART hand
Operators communicate with each other Set up. Monitoring, etc.
Technical Specifications
Measurement parameter: differential pressure Liquid level pressure
Measurement range: Lower limit value: Starting from -100% URL (continuously adjustable)
Upper limit value: up to+100% UFL (continuously adjustable by 1)

The minimum range of the differential pressure transmitter should be the minimum range in Table 1 and Table 2
The larger value. The range of adjustment shall not be less than the minimum range. Maximum quantity of transmitter
Cheng should be the minimum value between the maximum range of the transmitter body and the rated pressure of the flange.
