Sensorconverter-PPC Current/Voltage/Frequency Converter

The PPC Sensor Converter offers users the option of connecting third party sensors to the PPC Hydraulic Tester which are not equipped with a STAUFF sensor detection. These can have different output levels and can therefore also be easily measured with the Hydraulic Tester.

Analogue Signal Measurement

Measuring of electric signals from a third-party sensor (e.g. 4 – 20mA, 0 – 10V) with the Sensorconverter-PPC.

The Sensorconverter-PPC is used, for example, for to measure the current consumption on proportional valves or for determining the switching statuses of motors or pumps. This allows the PPC testers to read these third-party sensors. Typical applications for generating and measuring a force/displacement diagram or torque/volumetric flow characteristic curves.

The following input signals can be processed:

• Voltage (DC) -48 V to +48 V; CAN: ±0.5% FS; Analog: ±1% FS
• Current (DC) -200 mA to +200 mA; CAN: ±0.5% FS; Analog: ±1% FS
• Current (DC) -4 to +4 A, ±1.5% FS
• Long term stability 0.1% span/a

Frequency Signal Measurement

Measuring of electric frequencies from a third-party sensor.

The Sensorconverter-PPC is used to make frequency signals (e.g. from turbine flow meters, volumetric flow meters and speedometers) measurable for PPC Hydraulic Testers. The adaptor can process sinusoidal and square signals from 1 Hz to 5 kHz with amplitudes from 100mV to 24V.

The following input signals can be processed:

• Frequency 1 to 5000 Hz; 100mV to 24V
  CAN: ±0.1% FS @ < 100 Hz
  CAN: ±0.5% FS @ > 100 Hz
  Analog: ±1%
• Long term stability 0.1% span/a
