This range of recorder uses PT100 or PT1000 electrical temperature sensors.
Humidity, Pressure and Process inputs i.e. dc Voltage or Current can also be specified.
They are popular in applications where the recorder is mounted remotely from the sensor or where a particular pen response is required.
They can be ordered with various pen response times to record “product temperature”
They are powered from either 240 Vac, or 12 / 24 Vdc. Full battery backup is available as an option.
