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.


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.

Technical parameters

Type of measurementtemperature
Maximum measurement range-50 to 400C
Max pressure of measured medium2 MPa
Measurement precision0.25% from measured range
this combined precision accounts for non-linearity of measurement, hysteresis and repeatability
Long-term precision stabilityadditional error of less than 0,05% of range per year
Recommended calibration frequencyonce every three years

Sensors are appropriately packed individually into padded cartons.

The packaging includes all information required for proper use and servicing of the equipment.


The sensor is screwed onto the measurement place with appropriate spanner (24mm). The inner thread on the measurement place and sensor must match! Tightness of the connection is ensured by appropriate gasket – not part of the delivery. The dial body of the sensor must not be used for tightening of the unit to the measured place.
