ROTSN-P500

Passive room temperature sensor | PT500
The passive temperature sensor uses a PT500 platinum element with a positive temperature coefficient. As temperatures rise, the resistance increases proportionally. Housed in an IP30-rated plastic enclosure, it connects via screw terminal block and has a resistance of 500 Ω at 0°C. For optimal performance, use shielded cable with grounding on the opposing line side.

Description

Temperature-based fan speed control 
Temperature sensors are vital components in HVAC systems, ensuring that environments are kept comfortable, efficient and safe. Thermal comfort affects our health, well-being, and productivity. Indoor temperature is amongst the major factors thermal comfort and, consequently, the productivity of occupants. Meanwhile, behavioural adaptation is known to be the most critical contributor to the adaptive thermal comfort model. 
Most of the HVAC systems are temperature-based. These sensors continuously monitor the room temperature and automatically adjust the heating, cooling, or ventilation to maintain the desired conditions without the need for manual intervention. Just as you might manually adjust a thermostat to reach a comfortable room temperature, HVAC controllers use the temperature sensor readings to make precise adjustments automatically. This ensures consistent comfort throughout the space while optimising energy use. 
 
How does it work?
This temperature sensor measures ambient temperature via a platinum element (PT500). This sensor element has an electrical resistance of 500 ohms at 0 °C. It has a positive temperature coefficient. This means that the resistance increases when the ambient temperature increases. Any device with an input for ‘passive temperature sensors’ can read out the measured temperature.
 
How to connect?
The platinum temperature sensor element can be connected via a shielded 2-wire cable. The cable can be connected via the terminal block with screws. This terminal block is suited for cables with a maximum cross section of 1,5 mm². We recommend to keep the cable length limited. The longer the cable length, the higher the influence of the resistance of the cable on the measurement readout. This sensor doesn’t require a separate power supply.
 
Sleek, contemporary design
The enclosure offers a sleek, contemporary design. It has an IP30 protection degree against ingress of dust and moisture. It can be mounted on a wall indoors. To ensure optimal performance, it should be protected from direct sunlight.
