Overview

HF520-EX-DB+HC2-SM-EX is a duct type explosion-proof temperature and humidity transmitter. The HF520-EX-DB explosion-proof temperature and humidity transmitter can be used in Zone 1/21, while the HC2-SM-EX explosion-proof temperature and humidity sensor probe can be used for Zone 0/20 explosion-proof. The measurement range can reach -40..+85 ℃, 0.. 100% RH. The HF520-EX-DB+HC2-SM-EX duct type explosion-proof temperature and humidity transmitter product has two versions to choose from: with display and without display. The transmitter with display has a working and measuring range of -10..+60 ℃, 0.. 100% RH, while the transmitter without display has a working and measuring range of -40..+60 ℃, 0.. 100% RH.

Product Details

HF520-EX-DB+HC2-SM-EX duct type explosion-proof temperature and humidity transmitter/pipeline type 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-DB+HC2-SM-EX is a pipeline type local security explosion temperature and humidity transmitter. The HF520-EX-DB transmitter product has a Zone	Explosion proof certification for Zone 1/21, can be used for Zone 1/21, not for Zone 0/20, HC2-SM-EX probe can be used 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.
