Máy phát tín hiệu hiệu chuẩn đa năng PCE-123

Indicates the nominal value for simulations and measurement of input
electrical signals such as frequency and temperature

The PCE-123 process calibrator / nominal value indicator is a device that does need a mains connector and that is used to simulate regulation signals or units en the MSR technique with which it can test and calibrate almost any unit parameter and measuring instrument. The nominal value indicator provides an electrical output signal (mA, mV, V and frequency in Hz as well as temperature in °C or °F). The calibrator other automatic graduated functions, and selection of output signal jumps by percentage (0 to 100%) via the up/down keys and direct display of the output value. The device is easy to use and is operated via the keypad. THis device is attractive due to its high level of accuracy and its universal range of applications which no electrician or MSR department should go without, as well as within the industrial sector.

This device we have on offer is a high quality alternative to those which are normally found on the market.

PCE-123 process calibrator
 

Areas of application

- The first image shown is the PCE-123 calibrating our SLT acoustic installation. The measurement range is from 30 to 130dB (A) for an input signal of 4 to 20mA.
- The calibrator emits, in this instance, as signal adjusted to 50% = 12mA (range 4 - 20mA) that corresponds to an indicator of 50% =  65 (64.9) dB(A) of the unit indicated. The accuracy of the SLT can be seen.

- The second image shows an example of us testing the display of our high precision PCE-T395 thermometer. The calibrator is adjusted to type-k and with a thermal tension /temperature of 200°C.

- The PCE-T395 shows the value accurately and with that the device is ready to be sent to the client.

- In the last example we test the accuracy of a frequency measurement with our PCE-DM22 multi-meter with integrated data logger.
 

- The process calibrator is adjusted to an input signal of 20kHz and as it was shown on our multimeter.

- The above examples show a wide range of uses, in profession practice, for the PCE-123 process calibrator.
 

- The PCE-123 calibrator is highly useful in laboratories, in MSR workshops or to test measurement instruments in research and development.
