municipal trash. For disposal at end of life, please
return this product to the nearest authorized
electronic waste disposal service or contact your
Kistler sales office for disposal instructions.
2.4 Personal safety warnings
Hazardous environment.
Read and understand manual before operating!
High temperature pressure sensor Type 6021B...
Page 6 6021B_012-002e-06.22
WARNING: HAZARDOUS ENVIRONMENT
Risk of explosive atmosphere.
Adapters, isolation valves, or sealing rings that are
not compatible with process gasses will corrode and
fail. This failure may
result in gas leaks, fire,
explosion, or projectiles.
Prevent corrosion and failure by verifying that all
components
are compatible as described in the
installation procedures.
Do not connect or disconnect while circuit is live
unless area is known to be nonhazardous.
Important:
The sensor must not be modified in any way.
Otherwise the ATEX,
IECEx and all other Ex
approvals will become invalid.
Substitution of components may impair suitability for
hazardous area.
Explosion Hazard. Do not connect or disconnect
when energized unless the area is free of ignitible
concentrations.

6021B_012-002e-06.22 Page 7
3. Pressure sensor
Basic execution
Sensor Type 6021B… is a 2-wire, internally ground
isolated differential piezoelectric pressure sensor. The
sensor is equipped with an integral mineral insulated
hardline cable and is available with different cable
terminations.
Executions for operation in hazardous areas
(Ex-versions)
All sensors of the 6021BE... series are certified for use in
“potentially explosive atmosphere” acc. to ATEX directive
and IECEx Standards.
The sensors are certified as Ex ia (intrinsic safety) and
Ex nA (non Sparking).
3.1 Technical data
The sensors may only be used acc. to the technical
specifications made in the respective data sheet.
The technical specifications are given in data sheet Doc.
No. 003-590.
3.2 Ordering key

4. Operation
For proper operation it is necessary to first determine
whether the sensor is installed in a potentially explosive
atmosphere.
4.1 Operation in non-hazardous areas
4.1.1 General instructions for operation
The following instructions regarding the installation
and operation must be followed:
The sensor is hermetically sealed. The integral
hardline cable meets ingress protection ≥IP50 and
must be protected against adverse environmental
effects where necessary.
The sensor may only be used for its intended
purpose. Any violation will waive all warranties and
responsibilities of the manufacturer.
IP protection degree has to be maintained.
The EC
Type examination certificate must be
followed as well as any ‘special conditions’ that
may be specified.
4.1.2 Sensor execution
In non-hazardous areas, the sensor without Ex-certifi-
cation Type 6021B-... can be used.
4.1.3 Ground isolated measuring chain
For measurements of very small pressure fluctuations
and in environments with electromagnetic interference, it
is recommended to operate the measurement chain
completely ground-isolated.
This requires a differential charge amplifier. Depending
on the required application, Kistler recommends the
differential charge amplifier Type 5181, 5183 (Ex ia) or
5185 (Ex nA).
Measuring chain examples are shown in Kistler
document No. 960-201.

4.2 Operation in hazardous areas
4.2.1 Instructions for operation in hazardous areas
In addition to the instructions for proper operation in
Section 4.1.1
the following instructions must be
followed for installation and operation in potentially
explosive atmospheres:
The sensor can be used in intrinsically safe
circuits in zones 0, 1 and 2.
Installation and operation of the equipment in
hazardous areas must be executed in accordance
to the explosion protection standards of the
respective country.
Installation of intrinsically safe circuits must be
conducted by qualified and authorized personnel
only and in accordance with the instructions of the
contractor.
All electrical connections must be properly
connected.
No modifications are permitted on any equipment
that is certified for use in hazardous areas.
Defective sensors must be returned to the
manufacturer.
Temperature classes and corresponding ambient
temperature ranges:
T6: –55°C = Ta = +75°C
T5: –55°C = Ta = +90°C
T4: –55°C = Ta = +125°C
T3: –55°C = Ta = +190°C
T2: –55°C = Ta = +290°C
T1: –55°C = Ta = +440°C
T710°C: –55°C = Ta = +700°C
X: Specific conditions of use valid for Ex-nA and
Ex-ia:
1. For ambient temperature installation restrictions
of the 6021BE... HT p-Sensor see equipment
description on certificates.
2. Where the integral mineral insulated cable of the
602X HT p-Sensor has flying leads, these must
be provided with a degree of protection of at least
IP20 when installed.
3. Where the integral mineral insulated cable of the
602X HT p-Sensor with type of protection “nA”
has flying leads, these must be provided with a
degree of protection of at least lP54 when
installed.

5.2 Mounting/removal
For the mounting and removal of the sensor generally
accepted engineering practice must be followed.
Particularly when work is performed on electrical and
pneumatic equipment any special applicable safety
regulations must be observed. In Germany this applies
among other for ZH 1/94 "Sicherheitslehrbrief für
Handwerker".
5.2.1 Direct mounting for sensors with Lemo connector or open leads
The sensor is installed with the mounting screw (M12x1)
Type 6419A21A, which is included in the delivery content
of the sensor:
To ensure a leak tight installation the sealing ring Type
1147A21A must be used. It is recommended to use a
new sealing ring each time the sensor is installed.
High temperature screw paste Type 1059 must be
applied to the mounting screw.
