Jumo Programmable head transmitter with radio transmission 00537914
The head transmitter with radio measured value transmission is used in connection with a Wtrans receiver for stationary or mobile recording of temperatures with resistance thermometers or thermocouples. Alternatively, resistors up to 10 kâ¦, voltages up to 50 mV and by means of external shunt currents up to 20 mA can be measured. Customer-specific linearizations are 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 form on the RS485 interface as well as as analogue outputs. Optionally, two relay outputs can be used to signal different alarms. This head transmitter for industrial use consists of the transmitter with integrated transmitter unit and an antenna battery housing. The transmitter is designed for mounting in connection heads of form B and works in the ambient temperature range from -30 to 85 °C. Installation in customer-specific connection heads is possible. The antenna battery housing is connected to the connection head via a screw connection (M20Ã1.5). The transmission frequency of the Wtrans measuring system is 868.4 MHz. This frequency is largely insensitive to external interference and allows transmission even in harsh industrial environments. If the antenna wall bracket is used on the receiver side with the 3 m long antenna line, the range is 300 m in free field The head transmitter is powered by a 3.6 V, 2.2 Ah lithium battery (size AA). A setup program is available as an accessory for the simple configuration and parameterization of the head transmitter and Wtrans receiver on the PC. Optionally, the online chart function can be used to record measured values on the PC.This text is machine translated.
