Features of 4 products

The WPMZ series have 4 product lineups according to the measuring signal, installation requirements, customer's machine and equipment.
WPMZ is compatible with applications in various industries due to high performance as a multi-display digital panel meter and various functions.
WPMZ can use as [DC voltmeter], [DC ammeter], [Strain gauge meter], [Tachometer], [Flow meter] etc. and useful & high performance at sites as process measurement.


DC Voltage / Current Measurement

  • ・DC Voltage / Current input
  • ・High-speed sampling rate(1ch : 4000 times/sec, 2ch : 2000 times/sec)
  • ・Alarm log function

[WPMZ-1] is for measuring DC voltage / Current, and it is especially suited for High-speed sampling on the production line in factory manufacturing process.
We recommend using at parts inspection for shortening the inspection process by NG judgement and clearance judgement etc.


Strain Gauge Measurement

  • ・Strain Gauge input
  • ・Wave compare, Multi hold function
  • ・High-speed sampling rate (1ch : 4000 times/sec, 2ch : 2000 times/sec)

[WPMZ-3] is for measuring strain gauge, and it has wave compare and multi hold function.
It is suitable for Process control, Quality control and traceability etc. at the manufacturing site where mass production is carried out with constant cycle.


Rotation and Speed Measurement

  • ・Rotation and Speed Measurement
  • ・Pulse input
  • ・Line driver input

[WPMZ-5] is Digital panel meter for measuring Rotation & Speed.
By installing a rotary encoder in a line or device that uses a rotating mechanism such as a roll, the speed of the roll can be measured in real time and the rotation can be controlled.


Instantaneous and integrated flow rate

  • ・Flow rate / Flow total measurement
  • ・Pulse input
  • ・Analog input

[WPMZ-6] is Digital panel meter for measuring Instantaneous / Integrated Flow rate.
It is useful for flow rate / flow total measurement of tanks installed in equipment or production lines etc.
WPMZ-6 can measure two different liquids flow rates, to monitor the flow difference to stabilize the mixing process.

■ Application examples

Great improvement in process control
at production and inspection

The WPMZ series can be used in a variety of applications as instrumentation indicators (digital panel meters) for machines, devices, and factory production lines.
Input signals from various sensors, real-time display as well as operation processing and various log functions are convenient for monitoring and recording conditions.

■ DC Voltage/Current Measurement


Calculation function + Alarm log function > Can be used for Capacitor lead length detection!

Input signals (Ach, Bch) from the sensor to WPMZ-1.
Able to detect capacitor lead length by using calculation function (A-B). Also, WPMZ-1 has alarm log function to keep trend data before and after alarm of comparison judgement.

Alarm log function:Trend data can trace up to max. 8 alarms.
High-speed sampling > Small change of value can be measured!

ΔHigh-speed sampling of max. 4000 times/sec with 1ch input, and max. 2000 times/sec with 2ch input, by ΔΣ modulation.
Capture changes in instantaneous values such as press management and torque management.

■ Strain Gauge Measurement


Wave compare mode

Alarm output and waveform log function by comparing measurement waveform and comparison waveform.

Multi hold mode

Outputs each compare result for each hold value of each section and the comparison judgement setting value.

Judgement waveform creation

Function to create judgement waveform necessary for comparison

Judgement waveform creation
Alarm output
Alarm output

Output alarm as ‘NG’ judgement if there is more than 1 measured point which is out of judgement waveform.

Display Example:Displays the hold value in each section with the current measurement value. Icons will appear according to the hold detail section switching method.
