Data Sheet
Pressure transmitter Type EMP 2
For monitoring and control in marine and industial applications
The high accuracy pressure transmitter EMP 2 is designed for monitoring and control in marine and industial applications and oers a reliable pressure measurement, even under harsh environmental conditions.
The exible pressure transmitter programme covers absolute or gauge (relative) versions with zero and span adjustment with a 4 – 20 mA output signal.
It has all the necessary marine approvals. Special versions with integrated pulse-snubber available, designed for use in hydraulic applications with severe medium inuences like cavitation, liquid hammer or pressure peaks.

Applications
Application and media conditions
Figure 1: Pressure range
In cases where valves are closed momentarily, surges of a value in excess of that for which the pressure element is designed can occur. To avoid damage to the pressure element, a damper should be tted.
The device can consist of a exible pipe, a throttle, a shock valve, or a combination of these items. The amplitude of surges should never exceed the maximum pressure range of the pressure transmitter.

Identication
The type designation and code number of the transmitter is embossed on the side of the housing at the bottom close to the pressure connector.

Mounting
Type EMP 2 is equipped with a 3 mm stell bracket for mounting.
Pressure connection
Connector with outside cylindrical thread G ½, some types available with G A mano, and inside cylindrical thread G ¼, to ISO 228.
The primary insertion length of the connector corresponds to EN 837. Connection to the transmitter is made through a connector with a spanner at, 14 mm across ats.
When tting or removing pressure lines, the spanner ats on the pressure connector should be used to apply counter-torque.

Water systems
Water in the pressure element is not harmful, but in the event of frost a water-lled pressure element may burst. To prevent this the transmitter should be allowed to operate on an air cushion.
Steam plant
To protect the pressure element against temperatures in excess of the maximum temperature for the medium (100 °C), the insertion of a water-lled loop is recommended. In the example, Figure 3: Insulation against radiant heat, insulation against radiant heat is also shown.
Electrical connection
Figure 4: Wiring diagram
The transmitter has a wiring diagram, see above gure. Terminals P (positive) and N (negative) are connection terminals for the supply voltage.
The same leads are used for supply voltage and output signal. A function test can be performed between terminals N and T without cutting o the current loop.

Pulse-snubber
Pressure transmitter, Type EMP 2
Pulse snubber
Figure 5: pulse snubber
EMP 2 with the pressure range 0 – 6 bar and 0 – 10 bar at extended test pressure is provided with an integrated pulse snubber for protection of the sensor element against cavitations and air bubbles in the media due to extreme pressure peaks and pulsations. Such conditions may be caused by pumps or fast operation valves in both high and low pressure systems.
The integrated pulse snubber is designed as an 0.3 mm orice mounted in the pressure connection. The medium should not contain particles which may clog up in the orice.
The viscosity has only little eect on the response time. Even at liquid viscosities up to 100 Cst the response time will not exceed 4 ms.
