Probe for outside temperature measurements, ohmic output or a NTC thermistor with ohmic output
Room temperature probe with plastic cable junction box. Its thermowell is made of stainless steel in order to protect the sensing element and to withstand aggressive environmental conditions. The cable junction box is provided with a terminal (2 or 4 pins version) for electrical connection. Sensing element can be a RTD with ohmic output or a NTC thermistor with ohmic output.
