PTH805 quick connect differential pressure sensor, differential pressure transmitter
Product features: ■ Stainless steel isolation diaphragm integrated structure, suitable for harsh environments ■ Small size, high precision, high cost-
Product details
The PTH805 series of wind pressure sensors, differential pressure sensors, micro differential pressure sensors, micro differential pressure sensors, positive and negative pressure sensors, and differential pressure transmitters are assembled using pure imported (American) capacitive differential pressure chips, with a plastic casing. The two pressure interfaces are designed with a quick connect plug structure for the trachea, which can be directly installed on the measuring pipeline or connected through a pressure pipe. Widely used in the fields of pressure process control in the power and coal industries, such as boiler air supply and underground ventilation.
