Features:
- dedicated range of counters with many variations available to order
- non-volatile count (count is retained if power is lost)
- counts up to 4,000,000,000 pulses (suitable for use with a small scaling factor, e.g. for flow measurement applications)
- count up and count down inputs
- compatible with quad bidirectional signal
- batch and pre-batch outputs
- facility for external start, stop and reset switches
Applications:
- production counter
- length measurement
- flow totaliser (scaled in barrels, litres, ml, etc)
- cut-to-length systems
- batch counting with slow down signal at pre-batch set point
Options:
- quadrature counters for count-up or count-down integrity check
Features:
- dedicated range of tachometers with many variations available to order
- dual-channel A and B inputs - 3okHz max single inout, 15 kHz max with dual inputs
- separate settings - all user-settable parameters are independent for each channel and each function
- dual function (frequency and ratio)
- high and low alarms (open collector)
Applications:
- indication of shaft rpm
- ratio of two shaft or roller speeds
- percentage difference between two shaft speeds
- linear speed of conveyor or process material
- flow rate measurement (scaled as required eg. litres/min, ml/sec, etc.)
- frequency deviation from a programmed mean
Options:
- quadrature tachometers for direction of movement detection
- averaging over long periods of time (ratemeter)
- "peak hold" tachometer
- latching, pulsed, or toggled alarm (open collector)
Features:
- dedicated range of timers with many variations available to order
- counts in milliseconds, displays seconds, minutes, or tenths of hours
- remote start, stop and reset
Applications:
- process control in timed steps
- warning of interim stages
- total lapsed time indication
Options:
- latching, pulsed or toggled alarm (open collector)
2000V Velocity Meter
- The 2000V is a variation on the standard 2000T tachometer. It measures the time between pulses generated by an object passing between two sensors and from this calculates the velocity of the object.
- The two pulses are usually applied to input A (I/P) and input B (I/P) - terminals 10 and 12 on the rear of the instrument, although it is possible to combine the two signals and apply them to input A only.
2000CT Combined Counter/Tachometer
- The 2000CT is designed to accept a pulsed signal from either one or two sources and the display can be switched to show the rate of the input signal or the total count as and when required.
- Both options are continuously monitored and either may be instantaneously selected by pressing a button on the front panel. A high and low alarm can be set for the rate value and the appropriate output will be activated when the value falls outside either limit.
