Most systems for data collection, regulation or indication require the temperature signal to be transmitted as standard 4… 20 mA. AUTEK provides temperature transmitter and / or indicator in the coupling head where the environment is acceptable for this solution. Otherwise we supply transmitters and / or indicators for rail mounting in cabinets.
Smar supplies temperature transmitters for HART, Profibus and Fieldbus Foundation which are Atex approved and can be used in hazardous areas.
The head mounted transmitters are supplied for fixed or adjustable areas. The fixed area transmitters can be adjusted ± 3% for fine tuning. The adjustable transmitters are trimmed for area and then fine-tuned to zero and range of potentiometers. The head-mounted transmitters provide clear benefits with noise-resistant 4… 20 mA all the way from the sensor head to the control room that can be over 1000 meters away. Additionally, closet space and assembly time are saved. The transmitters can also be supplied with HART communication.
The rail mounted transmitters are supplied for fixed or adjustable areas. The fixed area transmitters can be adjusted ± 3% for fine tuning. The adjustable transmitters are programmed for zero and range with dipswitches and fine-tuned on potentiometers. The transmitters are rail mounted in cabinets. This assembly offers clear advantages as the transmitter is pulled away from the often humid and temperature-varying process environment, but then the advantage of pulling 4 … 20 mA signal is very noisy until the sensor head.
