  • Select a product or scenario overview: TRH-P-208 dry gas special micro differential pressure sensor / transmitter

Pressure difference sensor, pressure difference transmitter is a high-quality pressure difference sensor developed by Honghuaheng, pressure difference transmitter

Pressure difference sensor, pressure difference transmitter price advantage, pressure difference sensor, pressure difference transmitter function stable

TRH-P-208 dry gas special micro differential pressure sensor / transmitter

Honghua heng differential pressure sensor / transmitter features:

1: Imported high-precision silicon piezoresistive differential pressure core in the United States, the accuracy can be higher than the peers, and the resolution is also up to a height.

2: Anti-jamming road system independently developed by Honghua

3: The outer casing is made of imported aluminum alloy, which is durable.

4: Honghua 珩 pressure difference sensor shell structure humanized design, the connection port is only 8mm diameter compression type cock structure M10*1 small thread assembly is convenient to measure the small pressure to disassemble.

5: Before assembling the square differential pressure sensor, high-density silica gel is applied to the joint surface, and four small nuts are used to solidify the four feet to achieve the moisture resistance of the sensor.

6: If the measurement and control is required, it is only a single tube type compared with the atmosphere.


Widely used in boiler air supply, downhole ventilation, central air conditioning, duct wind power, building automation and other power, coal industry pressure process, laboratory with air pressure requirements, indoor gas pressure control field for fire engineering.

It is also called: Honghua 珩 differential pressure transmitter, positive and negative differential pressure sensor, positive and negative differential pressure transmitter, central air conditioning differential pressure sensor, furnace differential pressure sensor, air duct differential pressure sensor, pressure difference induction Differential pressure sensor
