Brief description
The Wtrans B head transmitter with wireless data transmission is used in conjunction with a Wtrans receiver for stationary or mobile acquisition of temperatures with RTD temperature probes or thermocouples. Alternatively, resistances of up to 10 kΩ or voltages of up to 50 mV and up to 20 mA using external shunt currents can be measured. Customer-specific linearization possible.
The measured values are transmitted wirelessly to the receiver of the Wtrans measuring system. The measured values are displayed on the receiver and are available in digital format on the RS485 interface and as analog outputs. Alternatively, different alarms can be signaled with two relay outputs.
This head transmitter, designed for industrial applications, comprises a transmitter with integrat- ed transmission unit and an antenna-battery housing. The transmitter is suitable for mounting in form B terminal heads and has an ambient temperature range of-30 to +85°C. Installation in cus- tomer-specific terminal heads is also possible. The antenna-battery housing is connected to the terminal head with a screw connection (M20 × 1.5).
The radio frequency of the Wtrans measuring system is 868.4 MHz. This frequency is largely im- pervious to external interference and allows data to be transmitted even in harsh industrial envi- ronments. When using the antenna holder for wall mounting with the 3 m antenna cable for the receiver, the open air range is 300 m.
A 3.6 V, 2.2 Ah (size AA) lithium battery is used for the head transmitter voltage supply.
A setup program is available as an accessory for easy configuration and parameterization of the head transmitter and the Wtrans receiver on a laptop/PC. The OnlineChart function can be used optionally to record the measured values on a PC.
