  1. 3045-101-00-CL1 | Sentry Pressure Governor System

    The Sentry Pressure Governor System is Class 1’s latest in state of the art fire pump pressure control. Operating on the J1939 network, the Sentry is able to monitor engine RPM and other pertinent data directly from the engine ECU. This allows it to react very quickly and accurately to any change in fire pump pressure. The Sentry Pressure Governor System consists of a Sentry display, Twister throttle, pressure transducers and associated wiring. It utilizes Class 1’s UltraView technology which is a custom tooled and programmed, 4.3 inch, full color LCD display with 8 buttons. The Sentry is packed with features that make it the most comprehensive and user friendly pressure governor to date. It has state of the art on board diagnostic features and is compatible with most engines.

  2. Twister ElectronicThrottle

    119970 / 119971 | Twister ElectronicThrottle

    The Twister Electronic Throttle (p/n 119970) is an SAE J1939 Controller Area Network (CAN) device that controls engine speed using data communications directly to the engine ECU for remote throttle applications. The Twister supports three CAN message formats: Torque/Speed Control 1 (TSC1) PGN 0 CAN message, Cummins Fire Pump Governor (CFPG), and Scania Body Control message. Control algorithms are optimized to take advantage of the J1939 CAN data to yield crisp and accurate control of engine. For engines that may not support the J1939 CAN data link control, an analog output signal version of the Twister Electronic Throttle is available (p/n 119971). The Twister utilizes Light Emitting Diodes (LED) to convey status information to the operator. The green THROTTLE READY LED is on the left-side of the control knob and the blue ACTIVE LED is on the right-side of the control knob. The Twister has a control knob and an idle button for the operator to control engine speed. The control knob allows manipulation of the engine speed within the configured (and engine allowable) RPM range. The idle button returns the engine speed to the configured idle RPM.
