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/EC of 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/EC on 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.
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
•With chemically aggressive environment that does not correspond the used metal 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 there is not free access of air and where there is some barrier of flow (area under the windows, niches in the
wall space close to furniture, etc.)
•where regarding to warm air from the interior space there could be occur a measurement error (the space above the
windows, doors, and ventilation openings)
•on the facade with the large thermal capacity, on the wall in which is placed for example chimney
•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
The sensor consists of a plastic head with the terminal block and of a metal stem, where is placed the temperature
sensor. The material of the metal stem is stainless steel DIN 1.4301 and the length of the stem is 25mm. The sensors
are connected as three-wire probes.The lead-in cable is connected to the terminals through the loosened grommet. The
material of the metal head is POLYAMID.
Sensor installation:
1. Before connecting the power supply cable open the plastic head. To open gradually slide a flat screwdriver into the
first and the second lid grooves and release the lid by deflecting the handles.
2. Connect the lead-in cable to the terminals according to the wiring diagram through the loosened grommet. To
ensure the ingress protection value of IP 65, the grommet must be tightened.
3. Place the sensor directly on flat surface using two screws Ø 4 mm placed in the inner hole in head corners. The
holes are available after opening the plastic head. The length of the screws must be chosen regarding to depth
of the internal holes of plastic head – the minimum length is 13mm
4. The lid must be put on after connecting the lead-in cable. The holds on the plastic head must
original position.
5.After installation and connection to the consequential electrical measuring device, the sensor is ready for operation.
The sensor does not require any special manipulation or maintenance. Operating position is arbitrary, it is
recommended to lead the power cable to the grommet from the bottom and
directed upwards.
