Wireless Remote Monitoring Sys

The TEL100C-RF system offers a completely wireless transmission setup to record data while subjects are mobile and/or physically distant (75 meters, nominal - 150 meters, line of sight) from the recording system.

A wide range of physiological activity can be monitored with the TEL100C, including ECG, EOG, EEG, GSR, SKT, PPG, RSP and surface EMG. Specialized signal processing of physiologic variables (like RMS filtered EMG, or QRS detection) can be performed on the computer via calculation channels.

The TEL100C-RF system (module set) has an upper frequency limit of 500 Hz for each channel. The TEL100C is not recommended for physiological measurements requiring higher frequency measurements (e.g. certain evoked response applications).

The TEL100C-RF system includes a portable amplifier/transmitter, which converts up to four channels of data into a modulated data stream. This data stream is transmitted to the receiver module, and then the receiver demodulates the data and sends it to the MP System for recording and analysis.

Up to four TEL100C-RF module sets can be used with a single MP SYstem, allowing up to 16 channels of transmitted data originating from up to four distinct locations. Each channel incorporates a switchable, non-distorting 50/60 Hz interference filter. Gain and bandwidth can be adjusted independently for each channel.

The TEL100C-RF will work with your current MP System and any other standard 100-series amplifiers. Use with BIOPAC SS Series Simple Sensor transducers and electrodes.

See Support > Application Note #126 for connection details, operational guidelines, and specification comparison with the TEL100C Remote Monitoring System in the Resource Tab.

  • BIOPAC does not recommend converting the wireless TEL100C-RF to a tethered system; TEL100C-RF components are not optimized for tethered physiological recordings. For tethered remote monitoring, use the TEL100C System.

   Performance levels for slow moving signals such as temperature, force, strain, pressure:

MP150/MP100 + amplifier/transducer—best performance; this exceptionally stable configuration provides better noise performance and stability for slower moving high signal/noise ratio signals (such as temperatrure, strain, force, and pressure).

TEL100C (tethered)—good performance; suitable for any signal recorded with an SS series transducer.

TEL100C-RF (wireless)—not recommended for slower moving variables, with the marginal exception of GSR and SKT.

Each TEL100C-RF System includes:

1 - TEL100D-RF receiver module
1 - TEL100M-C portable 4-channel amplifier/transmitter
1 - TEL100-RFL radio frequency link (wireless set includes TEL100T transmitter and TEL100R receiver)
1 - CBLTELISO 2-meter isolation connection cable (RCA-M to 1/4-M phono mono)
