Product Details

2016 Coal mine using GPD series negative pressure sensor

Application

Negative pressure sensors can be used to measure and control PRESSURE of liquids, gas, fluids in:

Electric power, water treatment,

Environmental protection,

Forklift weighing system,

Fuel pressure measurement

Oil & Gas and Hydraulic press,

HVAC systems, air condition,

Petroleum and chemical industry,

Other automatic control industries.

Description

1. Negative pressure sensors adopt advanced imported sensor component, which is combined with the solid state integrated technological and isolate diaphragm technology.

2. The negative pressure sensors is designed to work well for measuring all kinds of air, liquids, gas, fluids, even though weak-corrosive media under all-weather environments.

3. The temperature compensation resistance makes on the ceramic base, which is the excellent technology of the negative pressure sensors .

4. Various output signals, compact construct design, strong anti-jamming, which makes this pressure transmitter is suitable for all kinds of automation control industries.
