Explosion-Proof Dew Point Sensor — FA 515 Ex

Description

FA 515 Ex dew point sensor – a device for measuring dew point temperature under pressure in potentially explosive environments and various non-aggressive gases. The device can perform measurements even in extremely dry air (down to -80°CTd). The device can operate at pressures up to 500 bar. A measuring chamber is available as an accessory. When placing an order, it is possible to select the output signal value in % RH, °Ctd, g/m³, mg/m³, ppm V/V.

Compared to previous versions, the sensor is equipped with a more advanced sensitive element and electronic components. In particular, improvements have been made to the temperature compensation calculation algorithm. This has led to increased accuracy and signal resolution. The sensitive element is resistant to condensate and, thanks to the sintered steel cap, is protected from direct contact with dirt particles.
