Sensors of temperature, humidity and flow for air conditioning equipment

 

Sensors of temperature, humidity and flow for air conditioning equipment

In the last years our requirements for comfort of the environment in which we live, work or spend our leisure time increase quite significantly. Due to these reasons there are utilised more and more frequently various types of air-conditioning units or whole systems, whilst their correct choice has a great influence on savings of energy.

One of the tasks of air-conditioning, depending on the existing internal and external effects, is to provide optimal temperature in the air-conditioned room. The company Sensit s.r.o. is engaged in development and production of temperature sensors that are integral components of air-conditioning systems and units.

The most important customers of the company Sensit s.r.o. include manufacturers of air-conditioning and cooling units as well as installation companies that are supported by sale warehouses of our business representatives within territory of the Czech Republic and Slovakia and other countries not only inside the EU.

MEASUREMENT OF TEMPERATURE IN A ROOM

The stated sensors can have resistance, current, digital and frequency output. All sensors offer the possibility of casing two sensors and casing non-standard temperature sensors (DALLAS, TSic, KTY, SMT and others). The S 110 line of sensors is also manufactured in a design for explosive environments.

MEASUREMENT OF TEMPERATURE OF RETURN WATER

The temperature sensor TR 080 suitable for providing sufficiently fast response of the connected system to a temperature drop of return water under the permitted limit. The sensor is installed standardly in a tube collector of the water exchanger. Clamp-on temperature sensors of the S 140 or S 150 series can be fixed directly onto the piping. Advantages of these sensors can be found in their easy dismantling in case of any failure without the necessity to discharge the medium. The S 140 line of sensors is also manufactured in a design for explosive environments.

MEASUREMENT OF SUPPLY AIR TEMPERATURE

For measurement of supply air temperature in pipes and air-conditioning ducts beyond the heater sensors with stainless steel shanks and heads with terminal boxes can be used. In case of operation at low temperatures the sen- sors can be used for protection against frost. The S 120 line of sensors is also manufactured in a design for explosive environments. Moreover, we offer the PTS 4x and PTS 6x line of temperature sensors in both resistance and with the option of installing programmable IPAQ and APAQ converters.

HUMIDITY SENSORS

Sensors of the PTSV series are designed for measurement of humidity and tempera- ture in air-conditioning applications as well as other industrial or residential rooms. The sensors are produced in designs for surface installation or installation on piping, with current outputs. In combination with sensors for detection of the dew point these sensors are used where it is necessary to prevent any condensation on surfaces, condensation on critical places of the equipment or in buildings (air-conditioning ducts, close to fans).

FLOW SENSORS AND SWITCHES

Flow sensors are designed for contact measurement of flow rate of gaseous media. Flow switches are designed for switching on load when air flow set value has been achieved. By combining the flow sensor or switch and the central holder, it is possible to use the meter in air conditioning ducts or pipes with voltage outputs.
