Fast Response Temperature Probe - Metal Connector Head

Delivery in 3 to 5 weeks

Product features Fast Response Temperature Probe - Metal Connector Head

DESCRIPTION AND APPLICATION

These resistance sensors are designed to measure the contact temperature of liquid or gaseous substances. The structure of the sensor rod allows the sensor to be used for direct temperature measurement in ducts and also guarantees fast sensor response to temperature changes.

The standard operating temperature range is between -30 and 130°C. The sensors can be used for any control system compatible with the sensing element output signals or the output signals listed in the sensing element type table.

The sensors are designed to operate in a chemically non-aggressive environment.

DECLARATION, CERTIFICATION, CALIBRATION

The manufacturer provides an EU declaration of conformity.
Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology. The manufacturer offers the possibility of supplying the calibrated sensors.
