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.
Every pressure module is temperature cycled to enhance long-term stability prior to installation of surface mount signal conditioning electronics. The electronics control and regulate the supply voltage to the strain gauge bridge and provide a high level output proportional to the applied pressure. Temperature signals, taken directly from the silicon sensing element, allow the bridge output to be corrected for changes in balance and sensitivity due to temperature change.
Integral protection circuitry includes an array of in-line filters, providing a low impedance path to case at high frequencies. All supply lines are protected against reverse polarity and signal lines against high voltage transients, resulting in compliance with stringent EMI and lightning requirements.
The pressure sensing module and electronics are housed within the case assembly which, together with pressure and electrical connectors, is fully welded to ensure high reliability. All wetted and external surfaces are manufactured from stainless steel. Prior to acceptance testing, all transducers are environmentally stress screened to optimize long-term performance and to remove premature failures.
Flexibility of design is maintained without compromising customer choice of interface, pressure range and output type. The PMP/PTX 3000 series is flight qualified to the environmental requirements of RTCA DO-160. It meets the demands of even the harshest environment and offers an affordable measurement solution with minimal technical risk.
