1.2 Description
The head transmitter, WTX700 designed for industrial applications consists of the
transmitter with integrated transmission unit and an antenna-battery case. The
transmitter is designed for integration into the connection head. Integration into
customer-specific connection heads is also possible. The antenna-battery case is
installed on the connection head via a thread (M20 x 1.5).
The measured value is transmitted wireless by the receiver (WRX900), displayed
on the LCD display and provided on the receiver via the RS485 interface as well as
an analog output. The radio frequency within the ISM band (Industrial, Scientific
and Medical Band) is 868.4 MHz. This frequency is almost insensitive to external
interferences and allows transmission even in a rough industrial environment.
When using the antenna wall holder with the 10 meter long cable for the receiver,
the maximum open air range is 300 m.
A lithium battery 3.6 V, 2.2 Ah (size AA) is used for the transmitter power supply.
Transmitter (probe) and receiver can be configured with the optional setup
program (probe ID, transmission interval, measuring range and, if necessary,
probe type). The configuration data can be archived and printed. Changed
parameters can be overwritten again with the factory settings at any time. The
connection between transmitter and PC is established via a PC interface
(USB/TTL).
Configuration can be preset if stated at time of order.
