Radio Telemetry Systems

The Wireless Sensor Receiver (WSR) works as a receiver unit for GEN II transmitters to provides an analogue output for inputs to connected GEN II transmitters. The WSR is a self-contained mains powered receiver and output unit with built-in batteries providing 48 hours of operation in the event of a mains failure. An LCD is incorporated for real time metering of sensor values. Two models are available with either 8 or 16 inputs/outputs and both will provide a 0-5V or 4-20mA output for interfacing with a logger, PLC or other data acquisition system. The WSR unit can be used with most GEN II transmitters (Except pulse and event loggers). The GEN II System uses a licence free 434MHz one way transmission frequency.

The RC250 works as a receiver unit for the GEN II transmitters to provide a serial Modbus output for up to 160 active channels. The RC250 is a self-contained mains powered receiver unit with built-in batteries providing more than 24 hours of operation in the event of a mains failure. An LCD is incorporated to show signal strength and serial number of last transmitter received. The RC250 unit can be used with any GEN II transmitters. The GEN II System uses a licence free 434MHz one way transmission frequency.

The RX250-AL works as a receiver unit for the GEN II transmitters and has a built in data logger to handle up to 250 channels over 125 transmitters. The RX250-AL is a self-contained mains powered receiver unit with built-in batteries providing more than 24 hours of operation in the event of a mains failure. An LCD is incorporated to show signal strength and serial number of last transmitter received. The RX250-AL unit has option of a standard 247,000, half million and 2 million reading internal memory and can be connected to a GSM modem to provide SMS alarms. The RX250-AL units will work with any GEN II transmitters. The GEN II System uses a licence free 434MHz one way transmission frequency.

The LOG-HC2-RC series consists of a small self contained transmitters that connect directly to any of the HC2 range of HygroClip probes. Each transmitter can operate for up to 6 years on its internal battery and holds up to 500,00 readings with and internal flash memory. The transmitters sends the data via a 433.92 MHz (US Version 913 MHz) radio transmitters to a central receiver unit up to 100m away. The receiver units then interface with a LAN interface or via USB to a laptop running the HW4 software. Systems can consist of up to 100 digital wireless dataloggers.

The 505U radio telemetry module is an economical solution for the remote monitoring of process signals. The 505U can connect to digital, pulse or analogue signals from process transducers, and transmit these signal values up to several kilometers by radio. The 505U is contained in a heavy duty, weatherproof IP65 enclosure.

The ELPRO 105 range of telemetry modules provide remote monitoring and control by radio or twisted-pair wire, over short or long distances. Transducer signals connected at one module (input signals) are transmitted to another module where the signals are recreated as output signals, or passed via RS232/485 to a host device such as a PL C or SCADA system.

The 105U-G Wireless gateway products provide a wireless interface between various data buses used in process and automation applications: Profibus; Ethernet; Modbus; DF1; DeviceNet; Modbus Plus. The 105U-G includes an integral radio transceiver, and transfers transducer and control signals (I/O) using a highly secure and highly reliable radio protocol. Each unit has eight, discreet digital I/O individually configurable as input or output. The Wireless Instrumentation Backbone (WIB) allows direct communication to other Elpro 105U and 505U telemetry units allowing systems to be customised to any application.
