Temperature sensor with display and plunger

Temperature sensor with display and plunger *Step required

In production :  2 to 3 weeks
All of this resistance temperature sensors with screen and rod are designed to measure the contact temperature of liquid or gaseous substances. The combination of temperature sensor and central support is suitable for temperature measurements in air conditioning ducts. The combination of temperature sensor and thermowell is suitable for temperature measurements in tubes. The temperature sensing element is located in a metal rod with a length of 70 to 420 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.

temperature probe with display and plungerThe 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 maximum temperature around the head is between -30 and 70 ° C and should not be exceeded, even for a short time. The temperature sensors with screen comply with protection against penetration IP 65 according to EN 60529. The temperature sensors with screen are easy to install thanks to the unique design of the "S head".

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.
