User Probe Interface (UPI)
The UPI can automatically calibrate temperature sensors without the need for user intervention.
Simply connect the UPI to the front panel of any of the Tecal ‘H’ range of dri-block calibrators.
With the UPI you can realise a fully automated and unattended calibration of your temperature
sensors saving both time and money. Simply place the sensor into the block insert and connect
to the appropriate front panel terminals, switch the UPI on and select your sensor type.
The UPI accepts types K, J, N, T and E thermocouples along with 100 and 1000 ohm 3 and 4 wire
RTD’s. You can also connect the UPI in series with 4 to 20mA current loop sensors and the current
reading of the transmitter will be displayed. Sensor wires are connected using standard 4mm
banana sockets with screw down pillars.
