100 µS ultra-fast, auto zeroing, affordable automotive pressure transducer

When price, performance and accuracy matter, there is nothing that compares to the Ditex PDS500G Automotive Pressure Transducer - an extremely powerful high-resolution tool offering accurate, stable and reproducible results. Everyone can be able to have one at a remarkably affordable price!

PDS500G works with all modern automotive and industrial oscilloscopes, and it is not limited to the Ditex CarScope series lab scopes.

Usually each diagnostic test requires different pressure transducer but the PDS500G eliminates this need by giving you one ultra-high-resolution transducer that can be used for an analysis on many automotive systems.

PDS500G features auto zeroing and an extremely fast 100 µS response time from 10% to 90% of full scale. This allows an accurate measurement of rapidly changing signals within a broad pressure range.

An optional absolute pressure transducer PDS500A is availabe too. You can also order a conversion factor other than the specified one. For example: 500 psi = 5 V or 34.5 bar = 3.45 V

Note: This set does not include adapters for petrol or diesel engines in-cylinder pressure testing and fuel pressure testing. Additional adapters and extensions are available in the complete kit.
