Passive temperature sensor | PT500 | metal probe | 1 m shielded cable
Product description
These are shielded sensors that offer particularly stable temperature characteristics.
They measure temperature using a PT500 platinum sensor element. They have a positive temperature coefficient of resistance, meaning their resistance increases as the temperature rises.
At 0 °C, the resistance is 500 Ω.
The sensor element is encapsulated with resin inside a stainless steel tube measuring 53 mm × 8 mm.
The integrated cable length is 1 meter.
It is shielded and features two twisted wires (2 × 0.5 mm²). The cable shielding consists of tinned copper braids, acting as a Faraday cage to reduce electrical noise and electromagnetic radiation.
The insulation resistance is >10 MΩ.
These probes are designed for precise and reliable temperature measurement.
Additional specifications and description
How Does This Temperature Probe Measure Ambient Temperature?
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 possesses a positive temperature coefficient, meaning its resistance increases as the ambient temperature rises. Any device with an input for "PT500 passive temperature sensors" can read the measured temperature.
What Are the Temperature Sensor's Cable Specifications and Connection Details?
This temperature sensor has an integrated cable. This shielded 2-wire cable is 1 meter long, with a wire cross-section of 0.5 mm². This cable can be extended if necessary. The longer the cable, the higher the impact of the cable's resistance on the measurement reading. This sensor does not require a separate power supply.
What Are the Design and Protection Rating of the Sensor Probe?
The platinum sensor element is resin-encapsulated within a stainless steel tube (53 x 8 mm). It offers an IP65 protection rating against the ingress of dirt and water.
