AP-IHC Water Monitoring System
Our AP-IHC is designed to provide an
indication of a solution’s conductance and with an appropriate signal/output
module to provide control signal or alarm action. The maximum operation range
of this water monitoring system is 0-2,000,000 micromhos, linear, or 2,500 – 2,500,000
micromhos for percentage. It is made of two elements: the electronics case and
a cell; and the typical cell transmitter is not required.
Accurate Water Analysis
The water analyzer (water quality testing equipment) contains the main circuit board, signal preamplifier, indicators,
and meter. Mounted to the back wall of the case, is the main circuit board
hereafter referred to as the motherboard. This motherboard contains the
regulated power supply, the instrument fuse, an alarm circuit, and the
interconnection terminal blocks. A second module, preamplifier, is mounted to
this motherboard. A signal/output controller module is optional.
The signal/output controller module
provides signal or control output for this piece of water quality testing equipment. The remaining components of the AP-IHC Analyzer are the
meter, the panel indicator lamps, and the power switch, all mounted on the
swing-out door of the case assembly. Cables and connectors are provided to
interconnect the water analysis motherboard
with the front panel components and the preamplifier module with the cell.
The stainless or plastic
cabinets are for indoor or outdoor use, designed for wall, pipe,
or console mounting (see temperature limitations defined in technical data).
A gasket is provided between the door and cabinet. The door is secured by a
hinge and holding screws (refer to drawing 18682). A female connector for
the cell may be located on the case assembly bottom or the cell may be directly
connected to the preamplifier terminal block (see cell drawing). Also on the
bottom are conduit knockouts with 7/8-inch diameter access. Unit also available
as components only (no cabinet) for commercial applications.
The cells used with the AP-IHC
Analyzer system are either NPT type or valve insertion type (hot top valve).
Two cell styles are available. Style
(1) are "screw-in" type, MC-41K, MC-61K (both with connector
termination), and MC123K (with spade lug termination). Style (2) are the
"valve insertion" type, MC-114 (for use with L family valves), or the
MC-115G (for use with gate valves). Both "insertion" type cells have
connector terminations. The "screw-in" type has one-inch NPT screw
threads and mounts into a tee or tank wall fitting. The "valve insertion"
type cells are designed to insert coaxially into the McNab valves
aforementioned. These water quality monitoring
systems do not have to dewater piping systems.
In cases where the plant’s high-pressure
requirements do not permit easy cell withdrawal for maintenance, or where short
dead time demands good full in-line sapling flows, a valve-inserted cell
system, L-3p, should be used. This is known also as an linear injector cell
assembly and hot tap valve. L-1 valve also has a mechanical interlock, which
prevents extracting the cell until the L-3p valve is closed.
