P1AT Temperature Sensor Datasheet
Digital temperature transducer P1AT is a telemetry-enabled, battery powered temperature sensor, which is primarily used to measure temperature in distribution pipes of gases or liquids and sending the measured data over the wireless network into centralized measurement systems such as SCADA.
Wireless communication of the transducer is provided utilizing one of the LoRaWAN, Sigfox, Bluetooth, ZigBee, 805.15.4 or Wi-Fi (2.4GHz, 802.11b/g/n, WPA2)radio technology using various RF frequency spectrums.
Application
Temperature sensor P1AT is designed for precision measurement and wireless transmit of temperature of gases or liquids inside distribution piping. The main measurement body is made from stainless steel, so any medium can be measured which does not react with stainless steel type DIN 1.4301, also known as AISI 304 also known as X5CrNi18 10.
The sensor uses very sensitive platinum elements to measure temperature in the tip of the probe. This measured information is afterwards transmitted over wireless network to the final system for monitoring, metering or controlling purposes.
Mechanical information
The transducer is enclosed in a robust stainless steel enclosure. The back cover is made from UV-stabilized ABS-based plastics.
