1. Introduction
I. Shipping and storage; product inspection
The device is to be safeguarded against dampness, dirt, impact and damage.
Product inspection
Upon receipt of the product, check the contents of the box and the product particulars against the infor-
mation on the delivery slip and order form so as to ensure that all ordered components have been sup-
plied.
Notify us of any shipping damage immediately upon receipt of the product. Any damage claim received at
a later time will not be honored.
II. Warranty
Your meter was manufactured in accordance with the highest quality standards and was thoroughly tested
prior to shipment. However, in the event that any problem arises with your device, we will be happy to
resolve the problem for you as quickly as possible under the terms of the warranty which can be found in
the terms and conditions of delivery. Your warranty can only be honored if the device was installed and
operated in accordance with the instructions for your device. Any mounting, commissioning and/or
maintenance work is to be carried out by qualified and authorized technicians only.
III. Application domain of the operating manual
These supplementary instructions apply to explosion-proof transmitter Types ES, ES-PPA
and ES-FF built from 1st August 2016 onwards.
This manual supplements the operating manual for non-explosion proof level meters. If
you do not have a copy of this manual, please request one from Heinrichs Messtechnik
GmbH or download the instructions from our website. The instructions herein pertain pri-
marily to explosion-proof level meters. The technical data in the installation and operating instructions for
non-explosion proof level meters still apply insofar as the present instructions do not replace them or ex-
clude their application.
IV. Measures to be taken before sending your device to the manufacturer for repair
It is important that you do the following before shipping your meter to Heinrichs Messtechnik GmbH for
repair:
Enclose a description of the problem with your device. Describe in as much detail as possible the
application and the physical and chemical properties of the fluid.
Remove any residues from the device and be sure to clean the seal grooves and recesses thoroughly.
This is particularly important if the fluid is corrosive, toxic, carcinogenic, radioactive or otherwise haz-
ardous.
The operator is liable for any costs arising from substance removal or personal damage due to inadequate
cleaning of a device that is sent for repair.

2. Steps prior to operation
Prior to installation and operation, it is essential that the operator familiarizes himself
with all of the instructions and information contained in the manual for non-
explosion proof level meters as well as the present instructions.
If any part of either manual is missing, contact Heinrichs Messtechnik to request a
new manual. These manuals can also be downloaded from our website.
2.1 Installation, mounting, commissioning and maintenance
Installation, mounting, commissioning and maintenance are to be performed by a technician trained to
work with explosion-proof devices, or by a Heinrichs Messtechnik service technician.
Warning
Any maintenance or repair that could compromise the explosion-proof capabilities of the
device in a potentially explosive atmosphere is to be carried out by an authorized Heinrichs
Messtechnik GmbH service center or under the supervision of an expert in explosion-proof
devices.
Heinrichs Messtechnik GmbH accepts no liability for any loss or damage of any kind arising from
improper operation of any product, improper handling or use of any replacement part, or from
external electrical or mechanical effects, overvoltage or lightning. Any such improper operation,
use or handling shall automatically invalidate the warranty for the product concerned.

5. Scope of application
The ES transducer is used in flow meters of the BGN, BGF and TSK type series in the BA fill level indica-
tor and the DWF density meter. This covers the areas of volume flow rate measurement, fill level meas-
urement according to the principle of positive displacement and density measurement. The ES* transduc-
er is intended for installation in a housing providing a minimum IP class of protection from IP20.
6. Mode of operation and system layout
The electric ES-type transmitter serves to transform the needle position of the mechanical measuring
system into a proportional 4-20mA signal or to the field bus interface connection.
6.1 Measuring principle
The position of the float and/or lifting body is transferred to the needle axis through a magnetic system.
The ES transducer uses 2 magnetic field sensors to measure the field of a magnet attached to the needle
axis in order to generate an output current of 4...20 mA. The usual non-linear scale is in this case linear-
ised with a maximum of 16 data points.
The terrestrial magnetic field and moderately sized homogenous external magnetic fields are largely com-
pensated by the applied differential measurement of the 2 magnetic field sensors.
7. Electrical connection
7.1 ES type
The electrical connection of the ES type is provided through an intrinsically safe 2-wire supply and signal
circuit of 4-20 mA.
7.2 ES-PPA and ES-FF type
The ES-PPA and/or ES-FF types are “FISCO field devices”and the electrical connection is realised via an
intrinsically safe 2-wire field bus circuit according to the FISCO model.
As an option, devices may also be connected to intrinsically safe field bus circuits that do not correspond
to the FISCO model. In this case careful attention must be paid to the maximum electrical values (Ui, Ii,
Pi, Li and Ci) as described below.

10. Special conditions for safe application
10.1 Environmental impacts on the transmitter.
Environmental impacts, like the process temperature of the flow meter and the installed ES* transmitter
must be considered. See also item 7 of the measuring device’s general instruction manual.
10.2 Atmospheric conditions
In accordance with EN 1127, a “potentially explosive atmosphere“ is defined as a mixture of air and com-
bustible gases, vapour, mist or dust under atmospheric conditions. Such conditions are defined in EN
13463-1, para. 1, with values Tatm = -20 °C to +60 °C and Patm = 0.8 to 1.1 bar. Outside this range, safe-
ty parameters for most ignition sources are not available. Usually, variable-area flow meters operate under
operating conditions outside the atmospheric conditions of 0.8 to 1.1 bar. Irrespective of the zone classifi-
cation –safety parameters of explosion protection –are basically not applicable to the inside of the meas-
uring tube. Therefore operation with combustible products is only allowed if a potentially explosive air mix-
ture is not formed inside the flow meter. Where this condition is not met, the operator will need to assess
the ignition hazard in each individual case and give due consideration to existing parameters (e.g. pres-
sure, temperature, process product, materials of construction for the measuring tube).
10.3 Ground connection
In variable-area flow meters, it is possible under operating conditions for charge separation to occur in the
measuring tube due to the transport of non-conductive fluids and/or when the flow comes into contact with
non-conductive internals (e.g. liners, floats). For that reason, variable-area flow meters must be perma-
nently grounded by the operator by way of the process connections (flanges) in order to discharge electro-
static build-up. The operator is also responsible for extending the ground continuity of the process pipe-
line. If grounding cannot be made via the process connections (plastic process connections or undefined
connections), the flow meter must be connected to the local ground potential via the flanges. This connec-
tion only ensures electrostatic grounding of the device and does not meet the requirements for equipoten-
tial bonding.
11. Marking
Only devices bearing the Ex label may be operated in explosive environments.
Example type plates for the ES standard and ES-FF versions are presented below.
