The new Industrial IXLdp was designed for the measurement and control of very low pressure
The new Industrial IXLdp was designed for the measurement and control of very low pressure and flow in industrial and process plant environments. The Industrial IXLdp transmitter features a rugged NEMA 4X enclosure, built-in electrical terminal box isolated from the electronics and threaded process connections.

The IXLdp transmitter utilizes a state of the art variable capacitance sensor with a glass-clad silicon chip. The Si-Glas technology combines the inherent high sensitivity of a variable capacitance transducer with the repeatability of a micro-machined, single crystal silicon diaphragm.

The Si-Glas sensor is composed of sputtered metals and glass molecularly bonded to silicon. There are no epoxies or other organics in the sensor to contribute to drift or mechanical degradation over time. The silicon diaphragm withstands high overpressure as well as shock and vibration.
