The models of the HD48.. series are active transmitters and accept both direct and 24Vac alternating power supply; they have standard current (4…20mA) or voltage (0…10V) outputs, or a serial RS485 output*, depending on the model.
Available models:
- horizontal probe for duct mounting (TO),
- vertical probe for wall mounting (TV),
- probe with 2 or 5 m cable (TC),
- fixed contact Pt100 probe for solar panel (TFP)
For the TO and TC versions, two probe temperature ranges are possible: standard -20…+80 °C and extended -40…+150 °C (option E). Temperature range of the thin film 1/3 DIN Pt100 probe for solar panel: -40…+85 °C.
Also available with LCD display (option L). Electronics working temperature: -20…+60 °C.
