Contact probe with display

Contact probe with display *Step required

In production :  2 to 3 weeks
The fast response resistance temperature sensors with display are designed for the measurement of the contact surface temperature. The temperature sensing element is located in a metal rod with a length of 50 to 220 mm. The plastic head of the temperature sensor with display is equipped with a grommet or connector; the measured temperature is indicated on the 4 digit display located under the transparent cap of the head. The temperature sensors with display can be used for all control systems compatible with the output signals listed in the technical parameters table.

Contact probe with displayThe maximum temperature range for setting the current loop of the temperature sensors with display is -50 to 150 ° C. Within this range, the required operating temperature ranges can be programmed, while the minimum difference between the lower and upper limits of the temperature range is 10 ° C. The measurement temperature range with the temperature sensor with display is between -30 and 110 ° C and, simultaneously, the maximum temperature around the head is between -30 and 70 ° C and must not be exceeded, even for a short time. The temperature sensors with display comply with the 65 IP penetration protection according to EN 60529. The temperature sensors with display are easy to install thanks to the unique design of the head S ".

The sensors are designed to operate in a chemically non-aggressive environment, the use must be chosen according to the temperature resistance of the head and the metal housings.
