100 µS ultra-fast response time, affordable automotive pressure transducer

When price, performance and accuracy matter, there is nothing that compares to the Ditex PDS500x Automotive Pressure Transducer. Everyone can be able to have one at a remarkably affordable price - nothing compares to the PDS500x! It is an extremely powerful high-resolution tool offering accurate, stable and reproducible results.

PDS500x works with all modern automotive and industrial oscilloscopes, and it is not limited to the Ditex CarScope series lab scopes. Lab scopes with banana inputs require an additional Bananas to BNC adapter.

Usually each diagnostic test requires different pressure transducer but the PDS500x eliminates this need by giving you one ultra-high-resolution transducer that can be used for an analysis on many automotive systems. With a wide pressure measurement range, resistant to corrosive environments, 3x pressure overload, with compact and durable housing, the PDS500x is the cost-effective solution for pressure analysis.

It features 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.

PDS500A is an absolute pressure transducer which means that with normal atmospheric pressure applied to the absolute sensor, there will be an output voltage which corresponds to approximately 14.5 psi (1 bar) at sea level. In short, there will be around 290 mV bias being produced by the sensor when the unit is not connected anywhere.

It is possible to 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.
