2-Channel Digital Strain Meter
Model No. HV-EXP4626
Features Self contained portable meter Direct reading of strain or force 5 digit Liquid Crystal Display, (LCD), indicates 20,000 micro strain or Newtons x 1 N Half or Full Bridge operation with 1, 2 or 4 active gauges Individual calibration and tare zero for each channel Rechargeable, environmentally friendly nickel metal hydride battery and universal power supply operation Dynamic strain output on one channel Expandable to 18 inputs Three year warranty ; Applications Energizing electrical resistance strain gauges in all configurations and analysing the bridge output for direct read-out on a digital meter For use with strain gauged force transducers To measure the frequency and amplitude of dynamic actions ; Description The strain gauge meter is a rugged direct reading instrument capable of measuring up to 20,000 micro strain with a resolution of 1 digit. It has two channels and can be used with any standard foil gauges in Half or Full Bridge circuits and either 1, 2 or 4 active gauges including gauges on force transducers. Each channel has a simple calibration and zeroing (tare) system. Both channels have DC excitation for static work, while one can alternatively provides an analogue output for dynamic work up to at least 10 Hz. It comes complete with two Half Bridge connecting cables. The instrument is mains operated with a rechargeable Ni-MH battery so it can be used for field work away from a power source. Low power consumption allows at least 8 hours use. By adding the 16 Channel Expansion Unit the meter becomes an 18 channel unit but still with individual calibration and Tare on each channel automatically called up when the channels are selected. Services Required; 12 V Electrical supply for running on line or charging battery pack, Single Phase 100 / 240 V AC - 50 / 60 Hz..
