Frequency Output Pressure Sensors

• While many pressure sensors rely on current or voltage output, frequency output is sometimes necessary.
• VFDs commonly use frequency output for water pump control and hydraulic pumps.
• We offer 1-6 kHz frequency output for our industrial pressure sensors, in addition to other kHz ranges.

The most common output signals in pressure sensors are current or voltage. However, there are applications where frequency output is the preferred output signal. The prevalent choice is 1-6 kHz as a linear signal over the operating pressure range with an excitation voltage from 10-28 VDC. Other kHz ranges are available, too!

Applications That Commonly Specify Frequency Output

The most common application is one where a variable frequency drive (VFD) is in use. For this instance, the pressure sensor is useful in the VFD control panel. Examples include water pumping control skids and hydraulic pumps that are powering rams in waste management.

Advantages of a 1-6 kHz Frequency Output

• low signal loss in applications that have electrical noise
• A to D conversion not necessary, thus simplifying design and saving cost
• frequency output in use with long cable lengths without signal degradation

1-6 kHz Frequency Output is Suitable for use* in Systems that Currently Utilize These Models:

• Omega PX106
• Honeywell EAF Series
• Syncroflo 40-801-0300
• AST4700
