The high-speed response pressure signal amplifier is currently being shipped in large quantities and has received great acclaim.
The amplifier for reluctance-type differential pressure sensors in the DPC series from Soseki Research is designed to match our models such as P7D, P3D, and P90D differential pressure sensors. The DPC-1 is a rack-mountable amplifier that is also ideal for multi-channel applications. (Measuring Principle) When pressure causes the pressure-sensitive membrane to displace, a change in magnetic resistance occurs, resulting in a change in the differential inductance of L1 and L2. This change is output as a small carrier voltage change due to the carrier voltage applied to the bridge. This voltage is amplified by a carrier amplifier, synchronously demodulated (demodulated), the carrier component is removed by a filter, and then DC amplification is performed to obtain the output.
