Works with the PT-100
Compatible with most temperature sensors with an mV output, the A-Box-T converts the output voltage of a PT-100 temperature sensor into a 4-20mA current output.
The A-Box-T Signal Converter, housed in an IP65 all-weather case, is compatible with all passive EKO sensors, the PT-100 temperature sensor, and any other temperature sensor output with an mV output, converting it into a 4-20mA current output instead.
EKO’s universal 4-20mA and Modbus RS-485 RTU converters give complete flexibility and the option to combine different types of sensors within a multi-sensor network. Solar radiation and temperature sensors can be easily integrated, preserving or improving sensor accuracy while complying with industry output standards.
The converter models are housed inside an IP65 aluminium case with universal cable glands and robust input/output screw terminals which can easily connect to any cable and measurement system at the installation site. With A-Box-T Signal Converter, the sensor cable can also be extended over a long distance without any signal loss or potential electromagnetic interference.
In addition, the optional USB controller and EKO Sense software provide access to the converter settings and advanced sensor parameters such as temperature dependency correction and non-linearity correction for adjustment and verification.
