Temperature sensors and transmitters
Temperature sensors and transmitters
Room comfort control, automation of technological processes and efficient management of various devices are important solutions for modern automation. A controller, various sensors (temperature, relative humidity, CO2, differential pressure etc. and actuators are required to properly implement these solutions. All are connected to one circuit and if one of them is missing, the system will not work properly. The network of sensors in the operating parameter collects information about the state of the equipment and sends it to the controller. The data is compared with the set parameters, and in case of differences, a command is sent to the actuator. Mobus communication sensors become more and more popular in BMS systems.
Room temperature sensors
The room temperature sensor has been designed for wall mounting and is used to measure temperature in heating, ventilating and air conditioning systems. Different types of temperature elements are used in the SA series room temperature sensor. There are most popular two types of temperature sensors with temperature elements NTC10 and PT1000.

Antifrost thermostats
The antifrost protection thermostats TD series are suitable for the protection of hot-water heaters, air heaters in ventilation and climate control systems, heat exchangers in cooling systems. The thermostats can also be used to control electrical heating systems, switch acoustic or optical alarm signals and measure temperature in nonaggressive gases or liquid mediums. The frost protection thermostat switches when the temperature is sensed by a capillary for a minimum length of 30 cm drops below the temperature set on the knob. When temperature increases, the contact returns automatically to the initial position. The thermostat is available with 3 different sensible elements that allow usage in different applications. The version with a 1,8 m capillary length has a bulb that allows the use of a pocket. The versions with 3 and 6 m capillaries can be used in air ducts or battery exchangers.
