Mounting the Liquidew I.S. Sensor Assembly into the Sampling System

NOTE: If the analyzer has been ordered with a sampling system, the Liquidew
I.S. sensor assembly will have been installed and tested in the factory. In
that case disregard the following section and go to Section 2.3.3.
The Liquidew I.S. sensor assembly consists of:
1
Dew-point transmitter – Easidew PRO I.S.
2
Temperature transmitter
Sensor block
3
To assemble, proceed as follows:
a. Remove the protective cap on the dew-point transmitter (Easidew PRO
I.S.) before installation and retain for future use. Take care to prevent any
contamination of the sensor before installation (do not touch or handle
the sintered guard - located on the tip of the Easidew PRO I.S.).
b. The dew-point transmitter has a 5/8" UNF parallel mounting thread which
should be installed directly into the sampling block with the bonding
seal provided. The bonded seal provided should be placed over
the transmitter mounting thread before it is screwed into the
sampling block.
c. Finger-tighten the dew-point transmitter by gripping the spanner/wrench
flats on the body - NOT the transmitter body cover. Completely tighten
using a spanner/wrench until the bonded seal is fully compressed to a
minimum torque of 30.5 Nm (22.5 lbf-ft).

HIGH PRESSURE! High pressure liquids are potentially
hazardous. Energy stored in these liquids can be released
suddenly and with extreme force. High pressure systems
should be assembled and operated only by people who have
been trained in proper safety practices.
