A2108: Basic Model A2108-LSR: Basic Model with laser light source
The A2108 Non-Contact Tachometer converts RPM into an analog (voltage) output signal allowing you to use any Digital Multimeter, Data Acquisition System or Voltage Recorder as an RPM display. Optional Contact adapter allows you to measure contact RPM or surface speed.
The voltage output on the A2108-LSR Analogue Output version provides 1mv/rev = 6vdc @ 6000 rpm.
The A2108-LSR-232 version provides direct serial data output to your PC, a serial cable & a CD with Logging software is supplied with this model.
The A2108-LSR version is switched On manually, using the continuous mode feature. option, provided continuous measurement is taking place the Probe will remain in the ON mode. An Auto OFF feature provides shutdown if no activity is logged for 1 minute.
The A2108 is delivered as a complete kit including:
- A2108 tachometer
- Custom carrying case
- 4x AAA batteries
- Instruction manual
- Calibration certificate
- Reflective tape
