NPT adapter
The 316 SS G1/2 adapter replaces the removable protective cap and
converts the threads to 1/2”NPT male external, 1/4” female internal 0001
threads.

Surge Protector (Lightning Arrestor)1
This DIN rail mounted surge protector is designed to protect PMC 0007
transmitters to a maximum discharge current of 20 kA.

Conduit adapter
0011
316 SS 1/2” NPT male cable conduit adapter.
Must be factory installed

Terminal box
The terminal box, with IP 67 ingress protection and watertight ventilation
element, provides
a moisture-free electrical termination for the submersible pressure 0003
transmitter. It should be
mounted in dry environment or directly in the switch cabinet.

Additional weight
The additional weight increases the dead weight of the submersible pres-
sure transmitter.It simplifies the lowering into monitoring wells, narrow
shafts and deep wells. It effectivelyreduces negative environmental influ- 0009
ences on the measuring result from the measured medium
(e.g. turbulent flow).Stainless steel 316L, approx. 500 g, length (L) 130 mm

Adapter Converter
It is able to convert RS-232 signal to RS-485 balanced differential signal
and extend the communication distance to 1.2km.It uses a particular pump 0005
to gain power from RS-232 signal (RTS, DTR, TXD) without initializing the
RS-232 series interface.This interface converter does this without requi-
ring any AC or DC power.

Desiccant drying cartridge

Desiccant Pack installed on Vented Transducer cable.The cartridge will 0010
have to be field replaced as site environment requires.
