Digital Pressure Indicator DPI - Bedienungsanleitung
8 Friedrich Leutert GmbH & Co. KG
2.3 Pressure sensor
2.3.1 Design
The DPI is supplied with a pressure sensor and connection cable. By the
armored cable with plug the sensor is connected with the DPI hand-held
device.
The pressure sensor is suitable for temporary measurements on indicator
valves only (gas pressure measurements on internal combustion engines).
Measurements on hydraulic systems must not be carried out.
The quartz sensor is characterized by high accuracy, robust construction
and durability. Its calibration interval is 8000 operating hours. The cali-
bration check can only be carried out by the manufacturer. In this regard
please contact the manufacturer.
NOTE
The screw of the pressure sensor is sealed to prevent improper use
or handling. Breaking the seal will lead to loss of warranty.
