Product Details

HF520-EX-WA+HC2-LDP-EX intrinsically safe explosion-proof dew point transmitter

HygroFlex

The 5-EX series is a dual channel transmitter used for measuring dew point and temperature in potentially explosive environments with dust and gas. It is a new and advanced intrinsically safe explosion-proof product.

The interchangeable explosion-proof dew point temperature sensor probe is cast in stainless steel pipe and can operate/work in the 0/20 zone. The HF520-EX transmitter itself has obtained explosion-proof certification for Zone 1/21. Intelligent design with electrical isolation circuits allows measurement systems to operate in many applications without inherently safe power sources.

HF520-EX-WA+HC2-LDP-EX is an intrinsically safe explosion-proof dew point transmitter, and the HF520-EX-WA explosion-proof transmitter can be used in Zone	Zone 1/21; HC2-LDP-EX pressure resistant explosion-proof dew point temperature sensor probe can be used in Zone
Zone 0/20. The HF520-EX-WA intrinsically safe explosion-proof dew point transmitter is available with and without display options. Its operating temperature range is -10..+60 ℃ (with display version) and -40..+60 ℃ (without display version). HC2-LDP-EX Explosion proof	The measurement range of the dew point temperature sensor probe is -60..+40 ℃ Dp/Fp (dew point), -40..+85 ℃ (temperature), and the withstand pressure is 0.. 40bar.
