Pressure transmitter for general
industrial purposes with diagnostics
DST P300
The compact high temperature pressure
transmitter is designed for use in almost all
industrial applications, and offers a reliable
pressure measurement, even under harsh
environmental conditions.
The flexible pressure transmitter program covers
different output signals, absolute or gauge
(relative) versions, measuring ranges from 0 – 1
to 0 – 600 bar and a wide range of pressure and
electrical connections.
A robust design with an excellent vibration
stability and a high degree of EMC / EMI
protection equip the pressure transmitter to
meet the most stringent industrial requirements.
Running a powerful ARM-based microcontroller,
the DST P300 offers diagnostic functions and
performance features.
Features • Robust electronic platform for harsh electrical
environments
• Available output signals:
- 10 - 90% of supply voltage
- 4 - 20 mA
- Absolute voltage
• For media temperatures up to 125 °C
• A wide range of pressure and electrical
connections
• Enclosure and wetted parts of AISI 316L
• Fully digitally compensated
• Diagnostic functions
• Scalable performance features available

Technical data
Application
Cavitation, liquid hammer and pressure peaks may
occur in liquid filled hydraulic 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.
Media condition
Clogging of the nozzle may occur in
liquids containing particles. Mounting
the transmitter in an upright position
minimizes the risk of clogging, because the
flow in the nozzle is limited to the start-up
period until the dead volume behind the
nozzle orifice is filled.
The media viscosity has only little effect
on the response time. Even at a viscosities
up to 100 cSt, the response time will not
exceed 4 ms.

Output and diagnostics
Pressure output signal
- Defines the measuring range of the sensor.
Output clamp levels
- Limit the pressure output signal if the
pressure rises above or falls below the normal
range.
Sensor fault signal
- Output at this level signals a sensor fault.
The fault signal setting can be high or low.
Flexible output clamping and flexible fault
signal error level to application fit available.
