This Differential Pressure Transducers is for very low differential pressure measurements. They are especially suitable for applications in plethysmography and pneumotachography.
This Transducer has very small internal volume and volumetric displacement to achieve high frequency response. It is highly resistant to mechanical shock and over-pressure. A diaphragm of magnetically permeable material clamped between two symmetrical assemblies completes a magnetic circuit with each E-core. Application of pressure causes diaphragm deflection, increasing the gap in the magnetic flux path of one core and decreasing the gap equally in the other core. The magnetic reluctance varies with the size of the gap, changing the inductance ratio. The inductance ratio is then measured by an Carrier Frequency bridge amplifier in which an output voltage proportional to pressure is obtained. The CFBA Amplifier for the PLUGSYS or a regular bridge amplfier in combination with the Carrier Frequency Adapter Box on can be used.
All exposed parts of these Transducers are made from 410 stainless steel to prevent corrosion. They have a 3.1 m (10 ft) cable and are supplied individually with two pieces of 4.8 mm (0.31 in) ID hose for connection to a Pneumotachometer, see pages F40 to F41. Interchangeable Replacement Diaphragms are offered separately to change the Transducer’s operating pressure range.
