Keeping Watch Over Your Information


Sentinel Guards Your Competitive Advantage

The Itron SENTINEL is a solid-state, electronic multimeasurement, polyphase meter of exceptional  accuracy.  This self-contained or transformer rated meter is designed for use in commercial and industrial locations, including large industrial sites and substations.

The utility industry is evolving.  Deregulation uncertainties mean changes in billing and planning and increased demand from customers for more information, including voltage quality, and load profiling.  The  SENTINEL enables you to gather and deliver that information whenever and however it is needed.

Platform Flexibility for Ease of Upgrade

You can respond quickly to meet your changing needs.  The SENTINEL's platform flexibility allows for ease of upgrade and downgrade, all without returning the meter to the factory.  When your requirements  change, count on the SENTINEL with total firmware upgradability and MeterKey™ upgrades for measurement levels and options via optical port or remote.

R300Series Communication Board - The R300 Series Radio Frequency Transmission Module allows for a 3rd energy or demand quantity to be transmitted.  As part of the SENTINEL R300  Series, this module enables customers to remotely read energy and demand billing registers with walk-by and drive-by systems.  Additionally, customers can configure the R300 Series to transmit  cumulative and continuous cumulative demand values, as well as coincident demand values.  These meters are 100% compatible with the various ITRON® ERT handheld systems.

The R300 Series features include:

  • Broadcast energy only for demand meters (R300S)
  • Broadcast any two quantities (energy and/or demand) for Time-Of-Use (TOU) /Load Profile (LP) meters, including cumulative, continuous cumulative demand and coincident demand values (R300SD)
  • Broadcast any three energy quantities (energy and/or demand) for TOU/LP meters (R300SD3)
  • Tamper protection (Removal)
  • The ability to stop transmission on selected non-fatal and diagnostic errors
  • All components housed within the meter
  • Mercury-free tamper detection switch
  • Two additional input/output variations:
    1. Two Form C KYZ outputs and one Form A low-current solid-state contact output
    2. Two Form C KYZ outputs, one Form A low-current solid-state contact output, and two Form A KY pulse inputs

Modem Communication Board - The optional 300/1200/2400 baudsensing internal modem provides telephone communication allowing remote access to the SENTINEL meter.  The  SENTINEL modem supports the CCITT V.22 bis 2400 telephone communication standard for initiating and receiving phone calls.  The meter communicates using PSEM C12.21 standard protocol.

The SENTINEL modem supports phone line sharing, call windows, and phone home on event to a master station.

Key Features:

  • Phone line sharing
  • Call windows
  • Answer delays
  • Phone home on event
  • Off-hook detection
  • Five optional input/output boards:
    1. One Form C KYZ output and one Form A low-current, solid-state contact output
    2. Two Form C KYZ outputs and one Form A low-current, solid-state contact output
    3. Four Form C KYZ outputs and one Form A low-current, solid-state contact output
    4. Two Form C KYZ outputs, one Form A low-current, solid-state contact output, and two Form A KY pulse inputs
    5. Four Form C KYZ outputs, one Form A low-current, solid-state contact output, and two Form A KY pulse inputs

Input Output (IO) Communication Board - Load profiling and data storage for multiple electricity meters, water meters, gas meters, thresholds, EOI, diagnostics, and more.

 RS-232 or RS-485 Communication Board - The RS-232/RS-485 board adds up to two serial communication ports to the SENTINEL meter to provide additional methods for data retrieval and  programming.  The RS-232 standard and/or the RS-485 standard allows point-to-point and multi-drop cummunication.  The board also provides the ability to use other communication  equipment for data retrieval and programming, including Itron UtiliNet® technology.

Key Features:

  • One or two serial communication ports added to the SENTINEL meter using PSEM C12.18 protocol
  • Ports are configured for RS-232 or RS-485 through PC-PRO+ 98 software
  • Allows other communication equipment to be connected to the SENTINEL meter
  • Each port is addressable
  • Five input/output board options:
    1. One Form C KYZ output and one Form A low-current, solid-state contact output
    2. Two Form C KYZ outputs and one Form A low-current, solid-state contact output
    3. Four Form C KYZ outputs and one Form A low-current, solid-state contact output
    4. Two Form C KYZ outputs, one Form A low-current, solid-state contact output, and two Form A KY pulse inputs
    5. Four Form C KYZ outputs, one Form A low-current, solid-state contact output, and two Form A KY pulse inputs

Multifunction Meter Module - The Multifunction Meter Module (MFMM) resides within the SENTINEL meter and transmits metering and diagnostic information via radio frequency (RF).   The MFMM operates in the unlicensed 902-908 MHz frequency range using spreadspectrum technology to integrate the SENTINEL Multimeasurement Meter into a Itron fixed network.

Key Features:

  • Supports advanced metering such as demand, time of use, and load profile
  • Provides active and reactive energy information
  • Monitors and transmits meter and SiteScan diagnostic information
  • Factory programmed for desired functionality
  • All components are housed within the meter
  • Optional outputs: Two Form C KYZ outputs and one Form A low-current, solid-state contact output

MeterKey™ - The MeterKey application allows customres to perform upgrades and downgrades of the SENTINEL meter in the field with the use of Itron SmartCard™ technology.   This capability reduces maintenance time and affords customers enhanced flexibility with their meter population; a standard meter type can be purchased and at the time of installation, the meter  can be tailored to fit the site needs (Advanced Measurement Levels, Load Profiles, Time-Of-Use, Per-Phase Voltage and Current, and Bidirectional Measurement capabilities).

Firmware Loader - As part of the PC-PRO+ 98 programming software suite, the firmware loader allows customers to upgrade SENTINEL meters with the newer versions of register  firmware.  This allows the utility to update product features with a simple optical port communication.
