Data Sheet

Temperature sensor Type MBT 153 and MBT 120

Temperature sensor element and pocket.

The MBT 153 is an universal cable temperature sensor that can be used for controlling cooling water and ventilation systems within general industry applications. This temperature sensor is based on a standardized Pt 100 or Pt 1000 element, which gives a reliable and accurate measurement.

On request the MBT 153 can also be delivered with NTC / PTC elements. The sensor is based on a stainless steel housing with a cable, which makes the sensor extremely exible.

The MBT 153 can be combined with a sensor pocket, type MBT 120, to protect the silicone cable from the media. The sensor combined with the sensor pocket is named MBT 5253.

The MBT 153 has a PVC or silicone cable as standard but it can be delivered with teon cable on request.

Features:

• For temperature measurement where reliable, robust and accurate equipment is required

• Temperature range -50 – 200 °C

• Short response times

• Pt 100 or Pt 1000 resistance element

• 2 or 4 wire connection

• MBT 120 sensor pocket available

Silicone

4 x 0.15 mm2 Resistance per conductor R1 = 114.7 Ohm/km

The constant conductor resistance : R = 2 x R1 The total resistance in the sensor circuit is therefore: R + RTD 3 & 4 wire sensor circuit are not relevant since the controller automatically compensates for the conductor resistance
