Howell Instruments Automatic Engine Data Acquisition Test System

H355 SERIES

Test Cell Instrumentation Package (TCIP)

Automatic Engine Data Acquisition Test System(AEDATS)

Howell’s H355 Series engine Test Cell Instrumentation Package provides an adaptable, internet protocol (IP) based platform for accurately testing and monitoring gas turbine engines. Designed to interface with multiple applications, our system automates test and calibration procedures, unifies evaluation standards, and provides power settings and target conditions for a wide range of engine types and parameters. This flexible system can be used in diverse capacities including engine test cells, power generating stations, nuclear power plants, and other various process industries.

The H355 Series can replace most test cell hardware including the following:

  • Variable Filter (Vibration)
  • Vibration Amplifiers
  • Calculation Counter
  • Temperature Indicators
  • Fuel Quantity Gauge
  • Compressor Inlet Total Pressure Indicator
  • Barometer
  • Engine Dyno Control Panel
  • Fault Light Panel
  • Ignition Start Timer
  • Engine Run Timer
  • Fuel Flow Discharge Pressure Indicator
  • Fuel Inlet Pressure Indicator
  • Compressor Discharge Pressure Indicator
  • Engine Stator Vane Position Indicator
  • Dyno Shroud Position Indicator
  • Lube Discharge Pressure Indicator
  • Lube Scavenge Pressure Indicator
  • Dyno Lube Inlet Pressure Indicator
  • Ng RPM Indicator
  • Nf RPM Indicator
  • T5 Indicator
  • PLA Indicator
  • H355 AEDATS TCIP

The H355 Series equipment can be utilized in many configurations.

One example is a Test Cell Instrumentation Package (TCIP) that replaces current gauges, indicators, and displays. This method presents all data on the monitor with the ability to instantly record all parameters. The TCIP is a cost-effective way to replace existing test cell instrumentation that has become obsolete or difficult to support.

Another configuration is an Automatic Engine Data Acquisition Test System (AEDATS), which adds an engine application computer program to the TCIP hardware. Currently fielded to the US Army’s Flexible Engine Diagnostic System (FEDS), this program prompts the test cell operator through each engine test, monitors the test results, keeps track of test progress, and alerts the operator of dangerous operating conditions. AEDATS performs all calculations and can present performance information corrected to standard day conditions.

The H355 will perform the following:

  • Monitor and display engine, facility, and calculated parameters
  • Scale, convert, and calibrate inputs to engineering units
  • Alert the operator of unsafe conditions
  • Remind the operator when transducers need calibration
  • Provides virtual instrumentation for visual reference and rate of change information

Other H355 features include:

  • Parameter inputs and channel assignments are software configurable
  • Printed Circuit Boards carry their own calibration allowing for off-site calibration
  • Microsoft Windows® operating environment
  • Prompts the operator through test procedures

H355 Optional Features

  • Engine application software
  • Standard or customized printed reports
  • Engine diagnostics using Howell’s patented Referred Engine Diagnostic Data (REDD)® analysis program
  • Second Liquid Crystal Display to enhance data presentation
  • Integradeable with other vendor’s systems
  • Integrated vibration system
  • Battery-backed uninterruptable power supply
