The E27H.1TBD5B e-Baratron® Ethernet-Enabled, 45°C Heated Absolute Capacitance Manometer, with an Etch Sensor features 0.1 Torr full scale pressure measurement with 0.15% accuracy, horizontal calibration, and a Swagelok® 8 female VCR® fitting. It features structures in the sensor housing that eliminate process byproducts from depositing on the surface of the diaphragm, minimizing drift. Updated temperature control electronics to provide superior long-term stability and repeatability. Based on established Baratron° capacitance manometer technology, the sensor's wetted surfaces are Inconel® for excellent resistance to corrosive gases. The contemporary stainless steel package provides a cleanroom-compatible product. The product is interchangeable with earlier 127, 627, and E27 Baratron® capacitance manometers and can be used with MKS power supplies, display units and pressure controllers, or the user's compatible power supply/readout devices.
