TEMPERATURE SENSOR TR050S Pt 1000/3850

Temperature Sensor

The temperature sensor with a cable for measuring temperatures of gaseous and liquid substances ranging from -50°C to 400 °C intended for universal application. SENSIT TR050S Temperature Sensor

Instruction Manual in Czech language is available here: www.cometsystem.cz/sondy.htm, or can be obtained from your supplier.

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.

Application:

The temperature sensors TR050S are designed for measuring temperatures of gaseous substances and solids. The temperature range for application of the sensor is -50°C to 400 °C, the maximum temperature may be exceeded up to 450°C in a short time – relates to active measuring part of sensor which is determinate by spacer ring. The sensors may be used for all control systems compatible with the Pt 1000 temperature sensor with a temperature coefficient of 3850 ppm / °C. Temperature sensors are developed for measuring temperature of smoke and flue gases in the flue fireplaces, stoves and boilers. They meet the ingress protection IP64 according to the EN 60 529 standard. The sensors are suitable for temperature measurement in chemically non-aggressive environments, the using must be chosen with regard to temperature and chemical resistant housing and a cable.
Recommended use and location of sensors:

Operating position is arbitrary
For correct function and long lifetime of the sensor it is necessary to keep insertion of the stem into the combustion throat at least 50 mm and also connected the sensor with a combustion throat of boiler.
Around the lead in cable with Teflon insulation can not be temperature higher than 260 °C

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
Where the sensor is exposed to flooding or jetting liquid

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.

Declaration of conformity
SENSIT s.r.o. provides the product with the EU Declaration of Conformity issued according to Act No. 22/1997 Coll.,
as subsequently amended. The product is in accordance with the following directives:

European Parliament and Council Directive 2011/65/EU of 8 June 2011 on the restriction of the use of certain hazardous substances in electrical and electronic equipment
Product safety and technical parameters were evaluated according to the following standards and norms, as amended:
EN 60751, EN 60529, EN 60730-1, EN 60730-2-9

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 DIN 1.4301. The sensors are connected as two-wire probes. The supply cable has external PTFE insulation and is shielded. The shielding is not connected with the housing or with the temperature element. The length of the housing can be chosen from 60 up to 200 mm.
Sensor installation:

Install the sensor in the measured location. For correct function and long lifetime of the sensor it is necessary to keep insertion of the stem into the combustion throat at least 50 mm and also connected the sensor with a combustion throat of boiler.
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 manipulation or maintenance.

Technical parameters:

Type of element	Pt 1000 / 3850 ppm / °C
Accuracy class of element *	± (0,15 + 0,0021t1) in °C for range -50 to 250°C

for two wire connection the influence of the cable resistance must be add to measured value, for example at temperature 25°C must be add the value 0,066 °C / 1m.
** applies to active measurement part of the case to the spacer ring

Operating conditions:

· temperature round the supply cable:	-50 °C to 260 °C
· relative humidity of the surroundings:	10 to 100 %
· atmospheric pressure:	70 to 106 kPa
