Hygro-Thermo-Baro transmitters from Thies Clima's COMPACT series are designed to measure relative humidity, air temperature and barometric air pressure.
The use of high-quality sensors for the parameters to be measured allows the sensor to achieve the following:
• High long-term stability
• Virtually linear characteristic
• Good dynamic behaviour
• Dewing resistance
• Low temperature coefficients
• Small hysteresis
Interfaces:
• digital outputs MODBUS RTU / THIES
• analog outputs
• plug connection
• calble connection
This sensor is above all intended for use at meteorological measuring stations for connection to data logger systems. Thanks to its universal interface the sensor can also be used as a single solution in every application suitable for the purpose.
The interface to the device is digital and consists of an RS485 interface in half duplex mode. In conjunction with ID-based communication the interface enables operation of the sensors in a bus system.
Two data protocols are available:
• ASCII (THIES format)
• Binary (MODBUS-RTU)
In addition to the digital interface, the transmitters with article numbers 1.1006.54.x4x and 1.1006.54.x6x have 3 analogue outputs which can be configured as a current or voltage output. The digital output can be used simultaneously with the analogue outputs.
The sensor is equipped with a integrated pressure sensor, as well as a replaceable hygro-thermo module for the capture of air temperature and relative humidity.
The replaceable hygro-thermo-module and the pressure sensor are factory adjusted and cali-brated. The sensor is supplied without a filter cap. The hygro-module is protected with its own white membrane. The sensor thus offers excellent dynamic behaviour. PT1000 measuring element is used for temperature measurement.
