Applied wherever there is a need for a high level of accuracy in an avionics indicator or calibration instrument. Functionality The CPA2501 can be configured with an altitude channel and an airspeed channel consisting of Ps/Pt or Ps/Qc. It can be configured as a single-channel altitude/altitude rate indicator, (Ps only) a single-channel airspeed/airspeed rate indicator (Qc only) or it can be a dual-channel unit configured as Ps/Pt or Ps/Qc. In the Ps/Pt version the airspeed/airspeed rate channel is a calculated channel. An optional barometer can be installed for display in the front panel or as a separate channel. Pressure ranges for each channel can be specified by the customer.

Communication The manual user interface is through a wide screen display with touchscreen. Navigation within the intuitive menu structure is easily learned. Recognizable icons, when touched, open screens for configuration and calibration. Communicating to a remote computer is achieved through Ethernet, RS-232 or optional IEEE-488 communications. Commands used for communication are the same as the previous version of Mensor avionics gauge models

Operator interface :! Menu ▼ Reading for optional barometer Local operation The intuitive operator interface of the CPA2501 provides visibility of one, two or three channels, each with or without the auxiliary display. Readings from the optional barometer can also be displayed in the lower right-hand corner. Pressure units for each channel and the barometer can be selected from a list of 38 metric and imperial units. The setup “apps” are continuously visible for fast configuration of various applications. Remote operation Remote control of the CPA2501 is achieved through the use of the IEEE-488,...

Reference pressure sensors Interchangeable sensor CPR8001 One or two pressure sensors can be chosen (see specifications). The interchangeable sensor CPR8001 are a special feature of the air data test indicator. Interchangeable sensors guarantee long-term operation with practically no downtime. The sensor can be removed for calibration and can be replaced by a freshly calibrated sensor. The ability to remove a sensor for calibration and replace it with a freshly calibrated sensor while the instruments remains in service saves time and money. Simply remove the four slotted screws on the rear panel,...
