Introduction
1.1
Scope of this manual
This manual covers the
EL-PRESS™
(including the EL-PRESS™ Metal Sealed) series digital pressure meters and controllers. It
contains general product information, installation and operating instructions and troubleshooting tips.
Standard
Metal sealed
1.2
Intended use
The
EL-PRESS™
is designed to accurately measure and/or control pressure in a fluid system using the media and operating
conditions (e.g. temperature, pressure) as specified at ordering time.
The gas(es) in the pressurized system in which the instrument is mounted must be clean and dry. The equipment is suited
for general purpose indoor (dry) applications, like laboratories and machine enclosures.
EL-PRESS™
instruments are suitable for use at temperatures between -10 and +70 °C and a relative humidity of 10 to 90%
RH, unless specified otherwise. The instruments have an ingress protection of IP-40, implying that the electronics housing
and electrical connection do not offer any protection against moist environments.
The wetted materials incorporated in the EL-PRESS™ are compatible with media and conditions (e.g. pressure,
temperature) as specified at ordering time. If you are planning to use the product (including any third party components
supplied by Bronkhorst, such as pumps or valves) with other media and/or other conditions, always check the wetted
materials (including seals) for compatibility. See the technical specifications of the product and consult third party
documentation (if applicable) to check the incorporated materials.
Responsibility for the use of the equipment with regard to suitability, intended use, cleaning and corrosion resistance of the
applied materials against the processed media lies solely with the end user.
Where appropriate, this document recommends or prescribes safety measures to be taken with respect to media usage or
working with the described equipment under the specified conditions. The end user is responsible for taking the necessary
safety precautions and proper use of appropriate (personal) protective equipment, even if such is not explicitly
recommended or required in this document.
The end user is considered to be familiar with the necessary safety precautions, and to comply with the appropriate
protective measures as described in the Material Safety Data Sheets of the media to be used in the system (if applicable).
Bronkhorst High-Tech B.V. cannot be held liable for any damage resulting from improper or unsafe use, use for other than
the intended purpose or use with other media and/or under other conditions than specified on the purchase order.

Product description
EL-PRESS™
series electronic pressure meters and controllers have a well-proven compact thru-flow design and are available
in pressure ranges from 2…100 mbar up to 8…400 bar, both in absolute and relative (gauge) pressure. A differential
pressure meter can also be supplied in the ranges of 2…100 mbar up to 0,3…15 bar.
This document also applies to
EL-PRESS™ Metal Sealed
series mass flow meters/controllers. These instruments are
characterized by their unique, patented, metal-to-metal sealing construction with excellent resealing capability.
Furthermore, the instruments distinguish themselves by a high surface quality and are therefore especially suitable for
meeting the semiconductor and solar industry requirements as well as other high purity gas applications.
