P1QT Temperature Sensor Datasheet
Digital temperature transducer P1QT 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 P1QT 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.
ATEX information
The device is available in ATEX version as following:
- ATEX zone 2: LoRaWAN and Bluetooth versions available
- ATEX zone 1: Bluetooth version available
- ATEX zone 0: Bluetooth version available
Certification is done according to the European Union legislation.
Mechanical information
The transducer is enclosed in a robust stainless steel enclosure. The back cover is made from UV-stabilized ABS-based plastics.

Packaging
Sensors are appropriately packed individually into padded cartons.
The packaging includes all information required for proper use and servicing of the equipment.
Installation
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.
