Legal regulations and standards:
•Electrical connection of the detector may only be carried out by a competent person with electrician qualification who
is familiarized with the "Instruction Manual" in detail.
•The Instruction Manual is part of the product and it is necessary to keep it for the entire service life of the product.
•The Instruction Manual must be transferred to any other owner or user of the product.
•The disposal must be performed in compliance with the Directive 2008/98/ECof the European Parliament and of the
Council - on waste and the Directive 2012/19/EU of the European Parliament and of the Council – on waste electrical
and electronic equipment (WEEE), as amended.
•The sensors are delivered in packages, which guarantee resistance to mechanical influences and that meet the
conditions with the European Parliament and Council Directive 94/62/ECon packaging and packaging waste), as
amended.
•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. laboratory (according to EN ISO/IEC 17025 standard) or in an Accredited laboratory.
Application:
The temperature sensors Ds 150B are designed for contact temperature measurements of smooth and plane surface of
solids. The temperature range for application of the sensor is – 40°C to 105 °C and it must not be exceeded even for a
short term. The sensors may be used for all control systems compatible with the DS 18B20 temperature sensor. They
meet the ingress protection IP65 according to the EN 60 529 standard. Sensors, includes fastening straps and closure,
are suitable for temperature measurement on pipes for operation in chemically non-aggressive environments.
Recommended use and location of sensors:
•To ensure accuracy of measurement is recommended to purify surface and use a thermal conductive paste or
silicone vaseline on a surface
•The minimum pipe diameter is 20 mm
•Operating position is arbitrary, sensor dimensions enables its location under the insulation on pipes
Warnings and restrictions:
The sensors must not be used for measuring in locations:
•Where the specified technical parameters and operating conditions are not adhered
•Where the sensor is exposed to mechanical action
•With explosion hazard
•For measuring temperatures of subjects under voltage
•With chemically aggressive environment that does not correspond the used metal and plastic materials
•Where the sensor is exposed to prolonged immersion in liquid or intense jetting liquid
It is not suitable to use the sensors for measuring temperature in locations:
•Where exposure to direct heat radiation from surroundings or to sunlight may occur
•Where the measured surface is not flat and its roughness does not provide a sufficient contact with the measured
surface
•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
