Howell Instruments H9000
AUTOTEMP/ AUTOTAK INDICATORS
The H9000 Series Indicators are solid-state analog/digital gauges that measure the output of ANSI type K thermocouples or frequency from a tachometer generator or magnetic pick-up.
Because temperature and speed are two of the most critical engine parameters used in monitoring mechanical integrity, prolonged engine life is dependent upon avoiding operation at these limits. Howell’s H9000 Series Indicators accurately provide these imperative measurements. The H9000 Series Indicators supply is ±1 °C, ±0.1 %RPM: pointer accuracy is ±6 °C, ±0.6 %RPM of digital display.
H9000 Series single purpose indicators have both analog pointers and digital displays for redundancy. Maximum response time is one and one-half seconds to stabilize within ±1 °C, ±0.1 %RPM at full-scale.
Other application examples:
- Oil Temperature
- Oil Pressure
- Fuel Flow
- Oil Quantity
- Engine Pressure Ratio (EPR)
- Fuel Quantity
