Event Detectors
105/106 Series
The 105/106 Series Event Detectors are the most versatile Event Detectors in the product line. These Event Detectors monitor the electrical resistance of up to 128 simple continuity loops, each comprised of single or multiple specimens under test. Each test specimen is continuously monitored while a selectable DC sense current is passed through each channel test-loop; resistance changes exceeding the selected threshold are recorded as an event. Minimum Event Duration, Channel Current, and Threshold Voltage settings can all be independently configured. 105 and 106 Series instruments are electrically identical, with the difference simply that the 105 offers four, 32-channel board slots and the 106 offers only one. Thus the 128-105 is equivalent to four 32-106 Event Detectors.

Loop Testing
Megger loop testers offer both traditional measuring techniques and state of the art “non-RCD Tripping” technology. Use these products to determine the prospective earth fault current, which is the maximum current able to flow in a phase-earth fault in an installation, and also to indicate the prospective short circuit current which is the maximum current able to flow in the event of a phase-neutral fault.

External Transmitter
terraTX-50
The terraTX-50 is a high power field transmitter capable of delivering 50Amps to a transmitter loop, designed to be used in conjunction with a terraTEM unit. The period is controlled by the terraTEM24, terraTEM or the optional inbuilt GPS synchronisation module within the terraTX-50. The ramp and the full Tx current waveform are directly inputted into the terraTEM24 or terraTEM. This makes the terraTX-50 simple to operate, freeing up operators from inputting key system parameters into the console after each sounding.

Loop-Powered Transmitters and Drivers
4-20mA
Loop-Powered Transmitters convert the output from proximity probes, seismic sensors, into a 4-20mA DC current, which is proportional to the input being measured. The transmitter converts the displacement or vibration signal to DC voltage and/or current for a DCS or PLC system. They control a 4-20mA current loop for a specified vibration range (ex. 0-5 mils peak-to-peak). The transmitters have a two-wire hook-up, powered solely by the loop current and have a power supply range of 15 to 36 volts.
