PTR-SD is a stainless steel Pt100 temperature sensor with Class 0.5 high precision, measuring range from 0 to 600°C. It adopts threaded installation structure for easy mounting on pipeline and equipment, equipped with a waterproof junction box to resist moisture and vibration in marine environments. The Pt100 platinum resistance element delivers stable linear temperature signals, widely used for temperature monitoring of ship engine rooms, fuel pipelines, exhaust pipes and heating systems. It can connect to ship control panels to realize real-time temperature display and over-temperature alarm functions.
