External adjustment relay alarm output Electronic pressure switch


pressure switch


The electronic pressure switch is a high-precision pressure sensor as a detecting component, and uses a high-stability circuit to generate a switching signal to realize continuous pressure measurement and switching quantity control. It has the advantages of high precision, small hysteresis, fast response, stable and reliable performance, small size, easy operation and easy installation and flexibility.

Widely used in chemical, mechanical, hydrological, electric power systems, gas pressure control and automatic control, external intermediate relays can complete a variety of control functions.

  • Externally adjustable structure is easy to use
  • Adjust no dead zone, zero to full scale set point can be adjusted
  • High precision and fast response than mechanical pressure switches
  • Reliable switching signal
  • Intrinsically safe explosion
