Enhanced
volume and weight calculations have the ability to include
the additional
amount of material contained in the roof sections of steep silo roofs below the
sensor mounting location

The HMI2
operator interface control
console provides convenient, local interface for Monitor’s “Smart”
RS-485
SiloPatrol® SMU SE cable-based inventory monitoring sensors
and/or Flexar® guided wave radar sensors. HMI2 allows
for monitoring up to 32 SMU SE and/or Flexar sensors. The
multi-functional HMI2 controls sensor operations,
displays measured and calculated data and performs/displays
system and sensor diagnostic messages via two separate
RS-485
communication networks.
The HMI2 display screen can be easily switched to view calculated
level, volume, weight or percent in addition to the basic distance
measurement. The HMI2 can be programmed to operate the SMU
SE “Smart” RS-485 sensors automatically, manually
or allow for both. Menu options allow the user to select days
of SMU SE operation (such as Mon.-Fri.), time window (such
as 7 a.m.-3 p.m.) and measurement interval (minimum 30 minutes).
Flexar’s measurements are updated automatic.
The built-in 16 point strapping table can be used to produce
volumetric or gravimetric calculated
readings if the dimensions of a vessel cannot be determined or the vessel is
of an irregular shape.

Auxiliary
Output Enclosure (AOE)
A unique feature of the SiloPatrol® SE or
Flexar® Inventory
Management Systems is the ability to incorporate both relay
and analog outputs with a standard "smart" output
sensor system. These auxiliary relay and/or analog outputs
are provided in optional Auxiliary Output Enclosures (AOE)
and are programmed and controlled by either the HMI2 or
SiloTrack™ PC-based
Inventory Management Software.
One analog output and up to four relays (two for HMI2;
four for SiloTrack) can be assigned to each of the “smart” output
sensors. These can be used to tie the Inventory Management
System into remote control systems, sound alarms and for
local control functions.
Up to 16 analog outputs or 32 relays can be provided within
a single enclosure. Up to four AOE’s can be connected
on a single network. The AOE can be located close to the point
of hardwiring termination minimizing wiring and installation
costs.

Warranty
Monitor Technologies
LLC warrants each HMI2 and AOE
it manufactures to be free from defects in material and workmanship
under normal use and service within two (2) years from the
date of purchase. The purchaser must give notice of any defect
to Monitor within the warranty period, return the product intact
and pre-paid transportation charges. The obligation of Monitor
Technologies LLC under warranty is limited to repair or replacement
at its factory. This warranty shall not apply to any product
which is repaired or altered outside of the Monitor Technologies
LLC factory, or which has been subject to misuse, negligence,
accident, incorrect wiring by others or improper installation.
Monitor Technologies LLC reserves the right to change the design and/or specifications
without prior notice.

Spotlight: True Fail Safe Level Switch
SafePoint®
"Truly" Fail-Safe Level Switch
The
SafePoint® rotary paddle level switch with a self-validating design
detects material presence plus continuously monitors its own ability
to function. The analysis includes sensor health and system power
failure, which makes the SafePoint truly fail-safe.
The SafePoint incorporates patented use of Hall-Effect technology,
dual outputs to indicate both material presence and unit health,
and microcontroller technology to continuously protect bulk solids
processing and storage from the consequences of unknown sensor
failure by providing immediate indication of a sensor failure
and confirmation of proper operation.
Other practical features of the SafePoint include rugged construction,
motor shut-off when paddle becomes impeded to maximize motor life, twist On/Off
cover for bolt free removal, and local status indicating light (except hazardous
location models)
A practical application for the SafePoint would be to use this "true"
fail-safe product if undetected sensor failure could result in a
catastrophic process problem.
