SIEMENS SITRANS P ZD Transmitters for gage and absolute pressure

SITRANS P ZD

SIEMENS SITRANS P ZD Transmitters

SITRANS P pressure transmitters, ZD series, are for measuring the gage pressure, absolute pressure and level of liquids and gases.

Transmitter with digital display and stainless steel enclosure. The SITRANS P ZD digital pressure transmitter is provided with a display and a 10:1 turndown. The enclosure and the process connection are stainless steel. The digital display is available either radially or axially to the process connection.

They are used to indicate and monitor the pressure measured at the point of installation. ZD pressu

SITRANS P ZD  Application

The ZD is a configurable pressure transmitter for measuring the gage and absolute pressure of gases, liquids and vapor.

It is equipped with a display for indicating the pressure value at the point of installation.
SITRANS P pressure transmitters, ZD series, are used in the following industrial areas for example:
• Chemical industry
• Mechanical engineering
• Food industry
• Pharmaceutical industry
• Shipbuilding
• Water supply

Design

The pressure transmitter is comprised of a thin-film measuring cell with a ceramic diaphragm, an electronics board and a digital indicator. All parts are accommodated in a stainless steel field housing (∅ 80 mm) with a glass cover and stainless steel process connection.

At the rear of the housing is the electrical connection for the voltage supply using a current loop 4 … 20 mA. The connection is made with a plug connector. At the front of the housing is the 5-digit display behind a glass cover. Underneath the display are the 3 keys for parameterizing the pressure transmitter. Above the display are a green and a red
LED for indicating the operating status.

The ZD pressure transmitter is available in two versions (see “Dimension drawing”):
In the radial version (type A) the display is fitted in parallel with the process connection. The display can be rotated by up to ±120° relative to the process connection. In the axial version (type B) the display is at right angles to the process connection. The display can be rotated by 360° relative to the process connection.

Function

SITRANS P pressure transmitters, ZD series, mode of operation Mode of operation
The ZD pressure transmitter has a thin-film strain gage which is mounted on a ceramic diaphragm.The measuring cell is temperature-compensated.

Functions
The ZD pressure transmitter has a 5-digit display behind a glass cover. The following data are shown on the display:
• Measured pressure
• Technical pressure dimension (default setting: bar)
• Limit violation in upward or downward direction, indicated by

LED and arrow symbols in the display The pressure transmitter is set using the 3 input keys behind the glass cover underneath the display. The key “M” is used to select the operating mode. Following modes of operation are available:
• Measured value
• Password
• Dimension
• Start and end of scale
• Upper and lower limit value
• Zero adjustment
The other two keys are used to set the values in the individual operating modes.
Two LED indicators are fitted above the display to monitor the set range and the status.
The green LED signals that the measured pressure lies within the set limits. The red LED lights up when the measured pressure lies outside the set limits and when there is an error.
