Product Overview
The Aplisens ATX-2 Head-Mounted Temperature Transmitter converts RTD resistance from Pt100 / Pt500 / Pt1000 / Ni100 into a 2-wire 4–20 mA output and supports programmable sensor type and measuring range. It is available with ATEX intrinsic safety approval (II 1G Ex ia IIC T6). For accurate selection and pricing, please call 865-900-8844 or email KSmith@CPSCalibrations.com.
The Aplisens ATX-2 is a compact head-mounted temperature transmitter designed to convert the resistance of an RTD temperature sensor into a standard 4–20 mA current output. The transmitter supports thermoresistance line compensation and can be configured to match your sensor type and measuring range. It is suitable for hazardous areas with ATEX intrinsic safety certification (II 1G Ex ia IIC T6).
