Product Overview

TR-1 Features

Our TR-1 provides exceptional performance, reliability and features. If you need to replace or overhaul an old failing instrument, consider buying one of our TR-1s from a company which has been designing quality aircraft instrumentation for over 40 years. Purchasing our TR-1 is substantially less expensive than overhauling or replacing your old needle gauge. We’re able to make this offer with a money-back guarantee because we’re confident you’ll love the performance, reliability and features these instruments offer.

Standard two-inch round (MS28042-1A mount), 4.23″ long.
Rugged and reliable design (unlike many old needle gauges).
Optional RS-232 input and output port to interface with EEC’s, FADEC’s and other devices.
Custom calibration (mapping) for unparalleled accuracy.
Optional two open-collector (pull-down) for controlling external warning lights or props (0.1 Amps max).
Optional ARINC 429 compatible via the BC-5 (contact EI Support for details).

Customer Testimonials

Working with EI representatives from the OSHKOSH show and sales representative has been a pleasant and positive experience. They have been very helpful, truthful and knowledgeable about EI’s products. I have yet to see the MVP-50P in action in our plane. Waiting for the Top Overhaul to be completed. We are glad we secured your product at the airshow. We had no idea, that a few weeks later, we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.

Beechcraft Bonanza C35

CGR-30C Cluster Gauge Replacement

Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
