The Series 3000 range of transmitters provide
comprehensive monitoring of toxic and Oxygen gas
hazards in potentially explosive atmospheres. Suitable
for mounting both indoors and out, they are available in
two versions and offer excellent versatility. The MkII is
contained in a flameproof housing, has an intrinsically safe
sensor connection and is for use in predominantly Zone 1
applications. However with the use of the optional remote
mounting kit the sensor of the MkII can be mounted in a
Zone 0 environment. The MkIII is for use with a separate
suitable IS barrier allowing the complete transmitter to be
used in Zone 0 applications.

These low powered gas detectors all feature a loop
powered 4-20 mA connection, making them ideal for
both new and retrofit installations. Users can configure
the detector through the use of the easy to read LCD
and intuitive interface while fault diagnostic software
and a programmable calibration period greatly simplify
maintenance procedures.

The intrinsically safe smart sensors are
supplied pre-configured and can be ‘hot
swapped’ without having to remove power to
the detector, saving time and money during
commissioning and routine servicing. A remote
sensor mounting kit is available that allows the
sensor to be mounted up to 15m (50ft) from
the transmitter, making it ideal for operation in
areas that are difficult to access.

Series 3000 is supplied with all necessary
accessories for easy installation. The detector
can be wall mounted using the integral
mounting lugs or pipe mounted (horizontal or
vertical) using the optional pipe mounting kit.
Electrical installation is made using the
2 x M20 cable entries (ATEX/IECEx version) or
2 x ¾”NPT conduit entries (UL/c-UL versions).
A suitable blanking plug is also supplied to
seal any unused entries. A weatherproof cap
is included for use in the harshest outdoor
conditions.

Mechanical Installation Options

Series 3000 MkII and MkIII are designed for use
in potentially explosive atmospheres. As such,
installation should follow national guidelines
using suitable mechanically protected cable and
glands (M20 or ¾” NPT) or conduit (¾” NPT).
Use 0.5mm
cross sectional area cable as needed to ensure
minimum operating voltage at the detector,
depending on installed cable length. Various
accessories are available for different applications.

Typical Maximum Installed Cable Lengths Series 3000 MkII

The maximum cable length between a controller and detector is dependent upon:

• The minimum guaranteed supply voltage to the detector at
the controller (V

• The minimum operating voltage of the detector (V

).

C

• The maximum current draw of the detector (I

• The input impedance of the controller (R

• The resistance of the cable (R

Using the example values, the table opposite shows typical cable lengths.

For a specific application, the cable manufacturer’s resistance data for a specific cable type
must be used.

A cable length calculation formula can be found in the product technical manual.

Series 3000 MkIII Cable Length Suggested barriers and isolators Series 3000 MkIII

The limiting factors in calculating maximum cable lengths when using barriers
and isolators are the total capacitance and inductance. Barriers and isolators
have a fixed amount of capacitance and inductance that can be connected to
their outputs. The cable between the field device and barrier/isolator will have
a value for capacitance and inductance per metre or kilometre that will be
available from the manufacturer or supplier.

To calculate the maximum cable lengths, calculate the total capacitance
and inductance for the length of cable, add any capacitance or inductance
due to the field device (in the case of Series 3000 MkIII capacitance and
inductance = 0). The resulting totals should not be greater than the value
shown for the barrier or isolator.

Listed below are some suggested barriers and isolators for use with
Series 3000 MkIII.

MTL7728+ (single channel zener barrier)
MTL7787+ (2-channel zener barrier)
MTL5042 (Galvanic Isolator)
Pepperl+Fuchs KFD2-STC4-EX1 (Galvanic Isolator)

Note: It is up to the user to ensure that the barrier or isolator used is suitable for

their application.
