Overview

HF520-EX-WB+HC2-SM-EX is an intrinsically safe wall mounted explosion-proof temperature and humidity transmitter produced by ROTRONIC, Switzerland. The product has Zone 1/21 explosion-proof certification and can be used in Zone 1/21, but not in Zone 0/20. The product has two versions to choose from: with display and without display. The working and measuring range of the display version is -10..+60 ℃, 0.. 100% RH, while the working and measuring range of the non display version is -40..+60 ℃, 0.. 100% RH. The HF520-EX-WB+HC2-SM-EX wall mounted explosion-proof temperature and humidity transmitter has been certified as explosion-proof in Zone 1/21. Intelligent design with electrical isolation circuits allows measurement systems to operate in many applications without inherently safe power sources.

Product Details

HF520-EX-WB+HC2-SM-EX intrinsically safe explosion-proof temperature and humidity transmitter/wall mounted explosion-proof temperature and humidity transmitter

HygroFlex

The 5-EX series is a dual channel transmitter used for measuring humidity 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 temperature and humidity sensor probe is cast in stainless steel tube, and the probe can operate/work in the 0/20 zone. The HF520-EX temperature and humidity 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-WB+HC2-SM-EX is a wall mounted explosion-proof temperature and humidity transmitter for this security system. The product has Zone 1/21 explosion-proof certification and can be used in Zone	1/21 zone, not available for Zone
Zone 0/20. The product has two versions to choose from: with display and without display. The working and measuring range of the display version is -10..+60 ℃, 0.. 100% RH, while the working and measuring range of the non display version is -40..+60 ℃, 0.. 100% RH.
