They are used to indicate and monitor the pressure measured at the point of installation. ZD pressure transmitters are available in an axial and a radial version. 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. 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. The ZD pressure transmitter has a thin-film strain gage which is mounted on a ceramic diaphragm. The ZD pressure transmitter has a 5-digit display behind a glass cover.
The following data are shown on 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:. The other two keys are used to set the values in the individual operating modes. 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. MPa, mmH 2 0, mH 2 0, psi, inH 2 0,. Particular value has been placed on a high surface quality.
The system can be electropolished in addition. A further important feature is the hygiene-based design of the process connection by means of various aseptic connections. The completely welded stainless steel housing can be designed up to degree of protection IP Exact adaptation of the pressure transmitter to conditions at the place of use is thus possible.
The electronics is potted to protect it against moisture, corrosive atmospheres and vibration. In the absolute pressure range there is no need for compensation with respect to atmospheric pressure. Note : These degrees of protection are only achieved under the following conditions:. Note : The integral EMC measures are only effective if the earth connection is made correctly.
Interference-free operation in systems and plants is achieved only if the specifications for shielding, earthing, cable routing and electrical isolation are observed during installation and assembly.
Note : Electrical equipment in hazardous areas must only be installed and operated by trained personnel. Modifications to units and connections result in cancellation of the explosion protection and guarantee. With intrinsically-safe circuits, make sure that equipotential bonding exists throughout the complete cabling inside and outside of the hazardous area. The limits specified in the ATEX approval must be observed. The zero error specified for the process connection should be considered as a guideline for a standard design.
We will produce a detailed system calculation on request. Systems with reduced remote seal errors are available on request. Connections for pipes: R01, R02 or R03, see table "Further designs" on next page. Please specify pipe classes see "Further designs". Welcome to ManualMachine.

The measuring cell is temperature-compensated. Mode of operation.
U const. Mode of operation U const. The output current and voltage are linearly proportional to the input pressure. Process temperature For gage pressure with metal measuring cell 0 mbar g 0 1. Measuring ranges for gage pressure only for US market SITRANS P pressure transmitter, function diagram The piezo-resistive ceramic measuring cell membrane has a Wheatstone bridge circuit, on which the operating pressure P1 and P2 of the media acts at both ends.
Each con- nection against the other with max. Certificates and approvals Approval CE conformity. 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 2 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. Functions The ZD pressure transmitter has a 5-digit display behind a glass cover.
Selection and Ordering data Order No. Measuring range to be set, Y0 1 specify in plain text: Y The use of high-grade materials guarantees compliance with hygiene regulations.
The use of high-grade materials guarantees compliance with hy- 2 giene regulations. Hazardous areas Note : Electrical equipment in hazardous areas must only be installed and operated by trained personnel. The pressure transmitter converts the pressure values into a 2 load-independent current. Used worldwide for greater flexibility, scalability, availability and safety in process automation.
