Flying lead temperature probe | PT500 | unshielded cable | 1 m
Product description
The supply voltage is 24 VDC. The stainless steel probe has a length of 85 mm. The measured temperature is transmitted via Modbus RTU. Both power supply and Modbus RTU can be connected via an RJ45 connector.
This passive temperature probe offers precise temperature measurement utilizing a PT500 sensor element. The platinum sensor is resin encapsulated and placed in a durable stainless steel tube measuring 53 x 8 mm to ensure reliability and longevity in various environmental conditions.
It has a positive temperature coefficient of resistance, i.e., when the temperature rises, the resistance rises. At 0 °C, the resistance of the probe is 500 Ω.
The length of the integrated unshielded cable is 1 metre and it has two twisted wires (2 x 0,5 mm²).
Additional specifications and description
How does it work?
This temperature probe 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 'PT500 passive temperature sensors' can read out the measured temperature.
How to connect?
This temperature sensor has an integrated cable. This unshielded 2-wire cable has a length of 1 m. The wires have a cross section of 0,5 mm². If necessary, this cable can be extended. 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.
Stainless steel tube, resin encapsulated
The platinum sensor element is resin encapsulated in a stainless steel tube (53 x 8 mm). It offers an IP65 protection degree against ingress of dirt and water.
