H1AT Temperature Sensor Datasheet
H1AT is a industrial-grade, fully calibrated digital temperature transducer; primarily designed to measure temperature in distribution pipes of gases and/or liquids. The solution offers a wide range of electrical connectivity options including RS485 and USB. The unit communicates using multiple protocol options. The unit offers multiple choices of physical connectors and can be used in a variety of environments.
Application
Temperature sensor H1AT is designed for precision measurement of temperatures of gases and/or liquids inside distribution piping or open air. The main measurement body is made from stainless steel, so any measured medium which does not react with stainless steel (DIN 1.4301) can be measured.
The sensor uses very sensitive probe to measure temperature in the tip of the probe. The sensor is fully calibrated and linearized.
Sensors are designed, assembled and tested in EU under full EU legislation.
Mechanical information
The transducer is enclosed in a robust stainless steel enclosure. Rest of the body is made from UV-stabilized ABS-based plastics.

Packaging
Sensors are packed individually into padded cartons.
The packaging includes all information required for proper use and servicing of the equipment.
Installation
Physical installation of the sensor
The sensor is screwed onto the measurement place with appropriate spanner (24mm). The threads on the measurement place and sensor must match! Tightness of the connection is ensured by appropriate gasket – not a part of the standard delivery.
The following tables show functionalities of the pins on the sensor side of the connection for different combinations of physical connectors and transciever types.
