PPED-2
Pneumatic Switch
Description
The pneumo-electric converter PPED-2 is designed to convert a continuous pneumatic unified signal into a discrete electrical signal at three arbitrarily selected points of the input signal range.
PPED-2: identification and purpose
PPED-2 is classified as a Pneumatic Switch and converts a discrete pneumatic signal into a discrete electrical signal. Select it by the complete designation, series, execution, marking and approved documentation. Similar lettering, housing or connector geometry does not establish identical operating data.
This historical category contains several types of transducing devices. PT, PO and PTS products relate to electrical-power conversion, while PMI, PMT and PMM designations identify vacuum-gauge transducers. Each page therefore follows the actual product function rather than the broad category name. A suffix, series number or extra letter can indicate a materially different circuit, pressure range, rating or interface.
Function and operating circuit
The item converts a discrete pneumatic signal into a discrete electrical signal. Exact input and output conditions depend on the execution. For a power converter, verify voltage, current type, frequency, phase arrangement, rated output, connectors and cooling. For a vacuum transducer, verify the measurement principle, pressure range, operating mode, vacuum connection and compatible measuring instrument.
Numerical values retained from the original catalogue record appear in Technical Details and must be compared with the passport for the actual unit. An aircraft platform or installation system is not assigned by analogy when a reliable source is unavailable.
Selection and compatibility checks
Before replacement, compare the primary and alternative designations, series, input and output ratings, dimensions, mass, connectors, mounting, cooling and documented environmental limits. For a vacuum sensor, additionally compare the conversion constant, emission current or heater resistance where the passport specifies those values.
Related members of one family may use different voltage, frequency, power, pressure range, mounting interface or purpose. The related links below support catalogue navigation and do not establish interchangeability. General technical background is available under Pneumatic Switch.
Incoming inspection and installation
Check the marking and supporting records, housing, connectors, terminals, vacuum fitting, mounting points, seals and any evidence of overheating, impact or corrosion as applicable. Bench testing must follow the documentation for the exact execution; an improvised test voltage or vacuum regime can damage the product.
Install the unit only in the intended circuit with the documented polarity, supply mode, load, cooling and safety provisions. After installation, complete the prescribed functional check. External integrity alone does not demonstrate serviceability or calibration.
Related catalogue positions
Functionally related catalogue products include PE-11M, PO-750A-2S, PTS-800BM, PMI-10-2. They are selected by actual type and family for navigation and do not imply compatibility. More positions are available in the Power Transducers category.
Enquiry information
An enquiry for PPED-2 should state the exact designation, quantity, required condition, marking photograph, delivery scope and required documents. When available, include the designation of the equipment and item being replaced. Price, actual availability, lead time and condition of a specific unit are confirmed separately.
Final selection must use the passport, illustrated parts catalogue or approved technical documentation. Missing ratings must not be inferred from a neighboring execution; request them together with a nameplate photograph and information about the installation system.
