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 a different pressure transducer but the PDS500G eliminates this need by giving you one ultra-high-resolution transducer that can be used for 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 available 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.
