•Full EMI and lightning protection •High accuracy and stability •Wide operating temperature range •Affordable solution with low technical risk •Gauge, absolute, and differential versions Our PTX/PMP3000 series has been the platform of choice, serving the Aerospace industry for the past 20 years. These products have been rigorously tested and qualified for use on a multitude of applications including: Hydraulic / ECS / APU / Engine / Landing Gear / Braking and others. This product range is tried and tested, used within the worlds most popular single aisle and twin aisle airframes. Quality and reliability is at the heart of everything that we do at Druck, these fielded products provide our customers and end users with reliability and peace of mind. At the heart of the 3000 series is an advanced high stability pressure sensing element, micro-machined from single crystal silicon in Druck’s own Class 100 processing facility. Resistors are diffused into the silicon diaphragm by ion implantation that forms a fully active four-arm strain gauge bridge. Single crystal silicon is perfectly elastic and has excellent mechanical properties. Druck technology offers the following features: •Excellent linearity •Negligible hysteresis •Enhanced long-term stability •High overpressure capability •Low mass offering fast response and low ‘g’ effect The micro-machined silicon sensing element is atomically bonded to a glass base and assembled into a high integrity glass-to-metal seal. Pressure media is isolated from the silicon element by a compliant metal diaphragm, resulting in a hermetic pressure module.
