Low-Cost Temperature Transmitters Receive ATEX Certification for Use in Zone 2 Hazardous Locations

ST130 series head-mount transmitters with thermocouple or RTD inputs are now ATEX-approved for use in potentially explosive atmospheres with flammable gases present.

Wixom, MI: Acromag's ST130 Series temperature transmitters recently received ATEX approval for use in explosive atmospheres. These thermocouple and RTD transmitters are USB-configured, loop-powered and provide a proportional 4-20mA output. The official ATEX certification is Ex II 3 G Ex nA IIC T4 Gc -40°C ≤ Ta ≤ +80°C (explosion-protected for Category 3G, Group II, Zone 2 gas atmospheres; non-incendive). ST130 temperature transmitters also carry CE and UL/cUL Class 1 Division 2 Zone 2 approvals. There are three models available and pricing starts at just $105.

“With the combination of ATEX Zone 2 certification for Europe and UL Class 1 Division 2 approval in the USA and Canada, our low-cost ST130 transmitters are now qualified for a wide range of applications,” explained Don Lupo, Acromag’s sales and marketing director. “Despite their small size and economical price, ST130s are ruggedly designed for use in hazardous and hostile industrial environments that require noise immunity, surge protection, and resistance to ambient temperature changes.”

ST130 transmitters mount in compact DIN Form B connection/sensor heads commonly used in thermowell applications for sensing temperature or when a protective enclosure is required.  Optionally, a DIN-rail adapter may be purchased for mounting on T-type or G-type rails.  For ATEX Zone 2 applications, the transmitter must be installed in an ATEX-certified enclosure with a minimum ingress protection rating of at least IP54.

ST130 transmitters are configured via USB cable with free Windows software and offer many high-performance features. These transmitters provide sensor excitation and perform advanced signal linearization, lead-wire compensation, and sensor fault detection functions. Units are very stable with nearly drift-free accuracy across wide ambient temperature changes and are highly resistant to RFI, EMI, ESD, and EFT effects. ST133 thermocouple input models additionally provide high-voltage isolation.
