OEM Pressure Transmitters for heavy-duty applications
Type DST P600, P607 and DST P650
The compact OEM pressure transmitter programme is designed for use in severe hydraulic applications. The programme consists of two series:
• DST P600
• DST P650
• DST P607 - without integrated pulse snubber, Cleanliness according to ISO 15001
The integrated pulse-snubber o•ers a high degree of protection against cavitations and liquid hammer, and the well thought out design results in excellent vibration stability and an exceptional robustness.
The high degree of EMI protection equips the pressure transmitter to meet most requirements. Running a powerful ARM-based micro-controller, o•ering diagnostic functions and intelligent performance features.
Features
• Designed for use in severe OEM applications
• For medium and ambient temperatures up to 125 °C
• Output signal:
◦ 10 – 90% ratiometric voltage
• Wetted parts made of stainless steel
• A wide range of pressure and electrical connections
• EMC protection up to 100 V/m
• EMC tested in accordance to Automotive ISO standards
• Fully digitally compensated
• Output clipping Min and Max

Applications
Figure 1: Pulse-snubber in DST P650
Cavitation, liquid hammer and pressure peaks may occur in liquid filled systems with changes in flow velocity, e.g. fast closing of a valve or pump starts and stops.
The problem may occur on the inlet and outlet side, even at rather low operating pressures.
The media viscosity has only little e•ect on the response time. Even at viscosities up to 100 cSt, the response time will not exceed 4 ms.
