--%>

These fast response resistance temperature sensors with display are designed for contact surface temperature measurement. The sensors, which are available including the fastening strap (40 cm) and a closing device are suitable for temperature measurements on piping. The temperature sensing element is located in a metal stem of length of 50 – 220 mm. The plastic head of the temperature sensor with display is equipped with a cable grommet 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 any control systems compatible with output signals listed in the table of technical parameters.

The maximum temperature range for current loop setting of the temperature sensors with display is -50 to 150 °C. Within this range, the required operating temperature ranges may be programmed, while the minimum difference between the lower and upper limit of the temperature range is 10 °C. The temperature range of measurement with the temperature sensor with display is -30 to 110 °C and, at the same time, the maximum temperature around the head is -30 to 70 °C and must not be exceeded even for a brief period. The temperature sensors with display meet ingress protection IP 65 according to EN 60529. The temperature sensors with display are easy to be installed thanks to the unique design of "S-head" made by SENSIT s.r.o.

The sensors are designed to be operated in a chemically non-aggressive environment, the use must be chosen with regard to temperature resistance of the head and the metal cases.

ACCESSORIES

DECLARATION, CERTIFICATION, CALIBRATION

  • Manufacturer provides EU Declaration of Conformity.
  • Calibration – The final metrological inspection – comparison with standards or working instruments – is carried out for all the products. Continuity of the standards and working measuring instruments is ensured within the meaning of the Section 5 of Act no.505/1990 on metrology. The manufacturer offers a possibility to supply the sensors calibrated in SENSIT s.r.o.’s laboratory (according to requirements of the EN ISO/IEC 17025 standard) or in an Accredited laboratory.
