| PFM120S
Hand Held Tachometer |
 The
PFM 120S Microprocessor based handheld tachometer is a versatile
instrument offering a very complete specification. A single
push-button enables speed measurement to be carried out from
1 rpm to 100,000 rpm.
By
simply placing a piece of reflective tape on the rotating
component and pointing the tachometer at it, very precise
speed measurements can be made.
A
beam alignment indicator shows the operator when the correct
positioning has been achieved.
The
floating decimal point LCD display gives constant four digit
accuracy over the complete speed range. The memory function
enables the tachometer to retain its last reading for up to
30 seconds.
A
very effective handheld tachometer, easy to use, extremely
accurate and with extended performance to very low and high
speeds.

| PFM125P Portable Sensor Monitoring System |
 The
PFM125P Sensor Monitor is a portable handheld display system
capable of giving direct readout from NPN open collector pulse
sensors.
Plug-in
interfaces are available which allow the instrument to sense
from 0-10V and 4-20 mA signals, as well as other types of
pulse signals and mechanical contacts.
 An
integral 3 button keypad is used to program the display to
suit the application.
Applications:
Pulse sensors are used for speed, rate, flow and energy monitoring
etc. Transducers with analogue outputs may be used for temperature,
pressure, level, etc.
A
versatile, programmable instrument for pulse sensors and transducers
with analogue outputs.
Features
of the PFM125P Include:
- Plug-in
interface for a range of sensor types
- Programmable
4 digit display for readout in Engineering Units
- Auto
calibration facility
- Fixed
or floating decimal point LCD display
- Variable
