Overview

HF520-EX-WB+HC2-IE-EX is an intrinsically safe and pressure resistant explosion-proof temperature and humidity transmitter. The HF520-EX-WB explosion-proof transmitter can be used in Zone 1/21; The HC2-IE-EX pressure resistant explosion-proof temperature and humidity sensor probe can be used in Zone 0/20 zone. The pressure resistant explosion-proof temperature and humidity transmitter is available with and without display options. The working temperature of the transmitter is -10..+60 ℃ (with display), -40..+60 ℃ (without display). The measurement range of the temperature and humidity sensor probe is -40..+85 ℃, 0.. 100% RH, and the withstand pressure is 0.. 40 bar.

Product Details

HF520-EX-WB+HC2-IE-EX pressure resistant explosion-proof temperature and humidity transmitter/intrinsic safety 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-IE-EX is an intrinsically safe and pressure resistant explosion-proof temperature and humidity transmitter. The HF520-EX-WB explosion-proof transmitter has a Zone	Explosion proof certification for Zone 1/21, can be used for Zone 1/21, not for Zone 0/20; HC2-IE-EX pressure resistant explosion-proof temperature and humidity sensor probe can be used in Zone
Zone 0/20. The HF520-EX-WB explosion-proof temperature and humidity transmitter product has two versions to choose from: with display and without display. Its operating temperature range is -10..+60 ℃ (with display version) and -40..+60 ℃ (without display version). The measurement range of the HC2-IE-EX pressure resistant explosion-proof temperature and humidity sensor probe is -40...+85 ℃, 0.. 100% RH, and the withstand pressure is 0.. 40 bar.
