On/off temperature controller thermostat PXR3

With the On/Off Control Thermostat, you can easily control the temperature of your process and be alerted when the temperature reading exceeds or falls below a certain level. With its clear display and simple controls, the PXR3 thermostat is easy to use and suitable for a wide range of sensors.

• Temperature alarm with on/off contact output
• Reduction of energy consumption
• Perfect for controlling your heating, ventilation and air conditioning loop
• Ideal solution for critical temperature monitoring and control applications

On/Off temperature control is an industrial temperature control principle that uses an on/off relay to control the temperature. The user sets the desired temperature set point. When the sensor reading is reached, the relay output is turned off and the system begins to cool. When the temperature reading drops below the set point, the relay output is closed and the system heats up. The principle of operation of this control loop is to repeat this action as many times as necessary to maintain the setpoint temperature and reduce this differential.

The hysteresis function offers the possibility of setting a temperature difference to avoid too frequent switching of the relay output and the controlled devices.

On/Off temperature control is not as precise as other methods such as pid control.

It is often used in industrial applications where precise measurement control is not required. Digital temperature control can be used to control the temperature value of gases, liquids and solids. In some cases, it can also be used to control the humidity of an environment.

One of the advantages of all-or-nothing temperature control is that it is relatively simple and inexpensive to implement.
