Piezoresistive Pressure sensor with Digital Display 4-20Ma Input PT-201L

product description

Piezoresistive Pressure sensor with Digital Display PT-201 pressure transmitter adopts the diffused silicon pressure sensor core of an internationally renowned company. It converts the pressure of the measured medium into 4~20mA, 0 ~10VDC analog signal and IIC, RS485 and other standard digital signals.Coupled with the versatile Herschmann plug, it ensures excellent product quality and optimal performance. Users can conveniently, quickly and accurately measure the pressure of various fluids. The ultra-high cost performance can be widely used in petroleum, chemical industry, metallurgy, electric power, variable frequency pumps, complete water supply, refrigeration, air conditioning, air compressors and other fields.

Pressure sensor with Digital Display Main feature:

  • The high-performance diffused silicon sensor core is equipped with a highly integrated bridge pressure sensor dedicated advanced chip for signal conditioning.
  • Digital temperature compensation and non-linear correction
  • A variety of signal outputs, equipped with self-molded plugs that are waterproof and breathable, perfectly adaptable to conventional sockets such as Hirschmann and HTP, and are widely applicable
  • High sensitivity, high precision, high stability
  • Full temperature zone temperature compensation, good electrical performance and long-term stability
  • Hirschmann plug, wide adaptability
  • Process connections can be customized
  • High cost performance, one year warranty
