DESCRIPTION AND APPLICATION
Resistance temperature sensors with display are designed to measure the contact temperature of gaseous substances in outdoor or industrial areas. The temperature sensing element is located in a metal rod with a length of 25-50 mm.
La plastic sensor head temperature with screen is equipped with a cable gland or a 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.
La maximum temperature range for adjusting the current loop of temperature sensors with display is between -50 and 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.
La measuring temperature range with the temperature sensor with display and simultaneously the maximum temperature around the head is between -30 and 70°C and should not be exceeded even for a short time. Temperature sensors with display comply with the ingress protection IP 65 according to EN 60529.
The temperature sensors with display 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 should be selected according to the temperature resistance of the metal head and cases.
