In production, medicine or agriculture, the measurement of ambient temperature or various materials is necessary to ensure high quality products or services. For such manipulations, it is necessary to use specialized thermometers that can provide the necessary information.
Thermometers contact TK-5 series
Contact thermometer TK-5.06 is used as a device for determining the temperature of various bodies, materials, gases, liquids and the environment. The process of measuring temperature indicators is carried out using probes of various types and types.
Use devices for various purposes, in particular, for temperature control and measurement of relative humidity:
- in industry of all kinds;
- at communal and heat power enterprises;
- during laboratory (scientific) research, etc.
Device and principle of operation
A contact thermometer of this type has a design of a housing with an electronic unit and a set of interchangeable probes used to measure the temperature of the required surface, medium or material.
As a thermosensitive element of the thermometer, a thermoelectric transducer with an NSC is installed in the probe. And for measuring ambient humidity, the device is equipped with capacitive humidity sensors . Moreover, thermometers of this type have a function that calculates the dew point temperature using the Hoff-Gretch formula.
The electrical unit of the device converts the signal coming from the input of the probe, the indicator of which is displayed on the display of the device.
Areas of use
Contact thermometer TK-5.06 is used in various fields of human life and work:
- Housing and communal services;
- thermal power industry;
- agriculture;
- oil and gas and coal mining industries;
- food and metallurgical industries;
- engineering industry;
- transport and construction industries.
Temperature control in the housing sector is carried out to determine the performance of the surfaces of pipes, engines, various equipment, as well as to measure the temperatures of liquids in the water supply and heating systems. As a rule, housing and communal services employees use the device to record the indicators of humidity in the environment and indoors or outdoors in ventilation.
In the heat and power industry, a digital contact thermometer is used to measure the data of various liquids in all types of water supply or ventilation systems.
In agriculture, temperature measuring instruments are used to measure temperature and humidity data in food storages and greenhouses of various types, to determine soil indicators, and also as a controller of indicators of life conditions in the process of raising livestock and poultry on farms.
The oil and gas and coal mining industries use a contact thermometer to determine the temperature of pipe surfaces during welding, to monitor the performance of air mixtures, various liquids and equipment surfaces. Also, the use of a thermometer is necessary in oil product storages, on tankers, in tanks, at car refueling stations, in wells and during production at mines.
In the food industry, temperature measurement is the main indicator for the quality production of goods. A contact thermometer is used to determine the performance of surfaces, liquids, air, bulk and viscous materials. Also, the device is necessary for monitoring dew point temperature, as well as fixing the relative humidity of the ambient air, during the control of technological processes in production, during storage and processing of products.
The machine-building industry requires temperature control during painting work, the manufacture of parts and workpieces and their subsequent heat treatment, during welding and for monitoring environmental indicators during climatic testing of products.
In the construction sector, asphalt laying processes, concrete production and building faience require constant temperature control, using a contact thermometer for this.
Smelting and bottling of non-ferrous metals require temperature control in metallurgy.
In the transport sector, thermometers are used to monitor during transportation various industrial products and food products that require specific indicators of storage temperature. In railway transport, a precise control of the temperature indicators of bearings on wheelsets of rolling stock and rail is necessary to avoid emergency situations.
Terms of Use
Contact thermometer requires certain conditions for its operation. So, the ambient temperature should not be lower than -20 degrees Celsius, but should not exceed +50 degrees. Relative humidity should be observed within 80% at a temperature of +35 degrees and atmospheric pressure kPa 86-106.
Functions and Features
The functionality of an electronic contact thermometer is quite extensive, which is why a mercury contact thermometer is used quite rarely. So, in the electronic thermometer there is a function that indicates the dimension of the measured values, there is also a measurement of temperatures from -40 to +200 degrees Celsius and above, measurements of relative humidity, fixing the minimum and maximum temperatures, calculating the dew point. The indicator of the device is equipped with a backlight and auto power off after 5 minutes of inaction.
Features
The main features of contact thermometers are their high accuracy, a built-in function that allows you to measure humidity and calculate the temperature of dew points, as well as an expanded configuration with several types of probes. The device is powered by AA batteries, while the device has low power consumption (about 350 hours of operation with one set of batteries). It has high accuracy indicators and an indicator with large characters on it.
