Acromag ST130 Series head-mount temperature transmitters

Acromag’s ST130 Series head-mount temperature transmitters have recently received ATEX Certification approval for use in explosive atmospheres. The 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).

The temperature transmitters are USB configured and loop powered, and provide a proportional 4-20 mA output. Three models are available - ST131 for RTD sensor or 100 Ω resistance input (non isolated), the ST132 for thermocouple or 100 mV input (non isolated), and the ST133 for thermocouple or 100 mV input (isolated).

The ST130 transmitters feature updated microcontrollers and ASICs to minimise temperature transmitter conversion errors, and offer a fast response with flexible I/O ranges. They also have a high immunity to surges, electrical noise, shock and vibration.
