The 840 series of pressure transmitters is specially designed for measuring pressure in explosive
atmospheres (safety class, EEx ia IIC T4, Ta=-20°C to +80°C) as part of a larger overall system. It
contains an integrated signal amplifier. The 840 series of pressure transmitters can be used in media
temperatures up to 85°C. If the pressure transmitter is used in other applications, the safety and
accident prevention regulations specific to that application must be followed.

The operator or owner of the larger overall system is responsible for following the safety
and accident prevention regulations that apply to the specific application.
When planning machinery and using the PT, follow the safety and accident prevention
regulations that apply to your application, e.g.:
• EN 60204, Electrical equipment in machines.
• EN 292, Machine safety, general design guidelines.
• DIN 57 100 Part 410, Protection against electric shock.
• EN 50 014:1997, General Requirements
• EN 50 020:1994, Intrinsically safe apparatus
• EN50284:1999, Special requirements fro Group II Category 1G
Mounting and electrical connection of the PT must be done by specialists with EMC training,
following all applicable regulations, and in pressureless, voltage-free, intrinsically safepressureless, voltage-free, intrinsically safe

Deviation of the supply voltage from the value given in the technical specifications, or
false polarity, can damage the pressure transmitter and cause malfunctions that can
pose a risk of explosion.
Operate only with an intrinsically safe, EMC compliant power supply with the
following specifications when employing the pressure 4-20mA output:
Supply voltage max.40 V DC
Current output max. 100 mA
Inductivity max. 0
Capacity max. 0.017 µF
For PT’s that are explosion proof Class I, Division 1, Groups A, B, C & D, the power
supply rating is 16-40 Vdc.
Do not lay connecting cables in the direct vicinity of cables carrying higher voltage or
used to switch inductive or capacitive loads.

should be exercised with the low pressure ranges. The flush diaphragm can be inadvertently
overloaded with thumb pressure, which can be the equivalent of several hundred psi.
