Datasheet
H1QT-ETH Ethernet Temperature Sensor Datasheet
H1QT-ETH 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 power over ethernet enabled device and report information using HTTP web page. The unit can be used in a variety of environments.
Application
Temperature sensor H1QT-ETH 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.
Technical parameters
| Type of measurement | temperature |
| Maximum measurement range | -40 to 120C |
| Max pressure of measured medium | 2 MPa |
| Measurement precision | 0.1% of measured range this combined precision accounts for non-linearity of measurement, hysteresis and repeatability |
| Long-term drift | less than 0,03 deg. Celsius per year |
| Recommended calibration frequency | once every three years |
| Operating temperature | -40 to 85C |
| Power supply | IEEE 802.3af PoE standard |
| Networking | 10Base-T RJ45 connector using IPv4 using static IP address or using DHCP for dynamic address allocation |
| Information access | JSON format using HTTP GET request |
| Mounting options | see order table below |
| Thread material | DIN 1.4301 (AISI 304 / X5CrNi18 10) stainless steel |
| Isolation resistance at 500V | RIZ > 2 M Ohm |

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.
