Differential pressure transmitters
Differential pressure transmitters monitor differential pressure and submit related electronic data to the system. In critical applications, for example, differential pressure measurement can be performed over a system filter. If the filter starts clogging and the differential pressure increases, an electrical alarm is sent to the system signalling the need for maintenance.
Also for level and flow measurement
Since differential pressure transmitters are very accurate and measure the smallest of differential pressures, they can also be used for level measurement based on the hydraulic pressure of the liquid. Especially in high-pressure systems, this measurement which is based on differential pressure is an excellent alternative to other level measurement methods.
In the case of flow measurements based on differential pressure, the differential pressure transmitter is also an essential component of flow measurement accuracy.
Programmable Aplisens’ differential pressure transmitters equipped with digital piezoresistant sensors are suitable for a number of industrial applications. The digital display that comes as standard equipment allows tuning of the appliance in field conditions without requiring any programming devices. The transmitters can also be delivered with factory-mounted 3-way or 5-way valve manifolds.
