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.

Application and media conditions

Pulse-snubber

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

Self-diagnostic default levels

* programmable filtering available

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.
