Application

The temperature sensors TG68 are designed for measuring temperatures of gaseous and liquid substances. The temperature range for application of the sensor is – 50°C to 150 °C and it must not be exceeded even for a short term. The sensors may be used for all control systems compatible with the Pt 1000 temperature sensor with a temperature coefficient of 3850 ppm / °C. The temperature sensors are designed for universal application. They meet the ingress protection IP68 h 5 m according to the ČSN EN 60 529 standard and sensors can be immersed permanently in the liquid up to depth of 5m. The sensors are intended for operation in chemically non-aggressive environments.

Sensor description

The sensor consists of a metallic housing with the sensing element inside and a supply cable. The sensor housing is made of stainless steel grade 17240. The sensors may be connected as two-wire, three-wire and four-wire probes. The supply cable has external silicone insulation and is shielded. The shielding is not connected with the housing or with the temperature element. The length of housing is 60 mm as a standard.

In the case of two-wire connection, it is necessary to add the effect of supply cable line resistance to the measured values, which is 0,027 °C / 1m at a temperature of 25 °C

Operating conditions

The sensors are designed for continuous operation in the environment defined by the parameters according to ČSN EN 60721-3-3 with the degree of strictness IE 37 and on the following conditions:

temperature round the supply cable: -50 °C to 150 °C
relative humidity of the surroundings: 10 to 100 %
atmospheric pressure: 70 to 106 kPa

Sensor installation

Install the sensor in the measured location.
Connect the wires of the supply cable to the evaluation unit according the wiring diagram. The supply cable shielding is not conductively connected with the external housing of the sensor or with the temperature element.
After installation and connection to the consequential electrical measuring device, the sensor is ready for operation. The sensor does not require any special attendance or maintenance. Operating position is arbitrary

Wiring diagram

Warnings and restrictions

The sensors must not be used for measuring in locations:

Where the specified operating conditions are not adhered to
Where the sensor is exposed to mechanical action
With explosion hazard (the supply cable is not resistant to flame propagation)
For measuring temperatures of subjects under voltage
With the operating pressure higher than indicated in technical parameters
Where the sensor could be exposed to permanent submersion in a liquid based on oil It is not suitable to use the sensors for measuring temperature in locations:
Where sufficient contact with the measured fluid is not secured (low submersion of the sensor, effects of the surroundings).
Where the supply cable might run parallel to mains cables (risk of interference signal induction and the measurement results may be influenced), the safe distance from mains power cables when cables run parallel can be as much as 0,5 m according to the nature of interfering fields.
Where the sensor might be exposed to effects of strong organic and inorganic acids with medium and strong concentrations at high temperatures, weak organic acids with high concentrations and high temperatures, chlorinated hydrocarbons, and undiluted alkaline substances.
Failure to follow the said recommendations will negatively affect measurement accuracy, reliability and service life of the temperature sensor.

Calibration

SENSIT s.r.o. performs the initial calibration of meters in compliance with § 10 Act 505/1990 Coll. as subsequently amended within the scope of their manufacturing processes. The calibration is performed by submersion of the measuring stem into a liquid bath. The continuity of operating meters is ensured in compliance with § 9, Sect. 4 in this Act.
