WTX700

Wireless temperature transmitter for use with WRX900 receiver.

• Accepts Signals From RTD, Thermocouple, Slidewire and mV Sensors
• 300m Line Of Sight Range
• 868.4MHz ISM Band for European Use
• Battery Powered
• Surface or Sensor Mounting Options

The WTX700 in head temperature transmitter is a new generation of wireless temperature measurement solutions from Status Instruments. It has been designed to accept most common temperature sensors as well as slidewire and mV signals. The measured process value is transmitted to the DIN rail mounted receiver WRX900 which can accept signals from up to 16 WTX700 transmitters.

A 3.6V battery is provided for the transmitter power supply and is fitted in a specially designed antenna housing which screws into the cable entry of our SCH11 (alloy) or SCH4 (ABS Plastic) connection heads.

The measured signal is transmitted on the ISM (Industrial, Scientific and Medical) band of 868.4MHz. This frequency is virtually insensitive to external interferences and allows transmission even in a harsh industrial environment. The open air range is 300m.

WRX900

Wireless temperature receiver with modbus and mA or voltage outputs

• Receives from up to 16 WTX700 Transmitters
• 300m Line Of Sight Range
• ISM Band 868.4MHz For European Use
• Programmable Current Or Voltage & 2 relay outputs
• RS485 Modbus Communication

The WRX900 receiver is used together with up to 16 WTX700 wireless in head temperature transmitters to provide wireless temperature measurement. The product converts the measured values received 2 current or voltage and 2 relay outputs as well as making them all available via a digital RS485 interface.

The product operates using the ISM (Industrial Scientific and Medical) band of 868.4MHz. This frequency is virtually insensitive to external interference and allows transmission even in harsh industrial environments. The antenna screws into the top of the DIN rail module but for use in cabinets or to gain the optimum signal, an optional 10m antenna extension lead with mounting bracket is available.

Programming is possible by PC using the configuration kit. However, it is also possible to programme the product using the push buttons following instructions on the LCD display. In normal use the LCD display shows channel number and process value.

Wireless temperature measurement eliminates the need for cables so is ideal for hard to reach places or moving objects
