Model IXLdp Ultra-Low Differential Pressure Transmitter
Brand: Ashcroft IncThe Ashcroft 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 Ashcroft IXLdp transmitter utilizes a state-of-the-art variable capacitance sensor with a glass-clad silicon chip.
The Si-GlasTM technology combines the high sensitivity of a variable capacitance transducer with the repeatability of a micromachined, 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.
