CL-Astern-Ahead RPM

Base Price $714.00

The CL-Astern-Ahead RPM tachometer is based on the popular CL-B101D40 circular, tricolor bargraph meter with 4 digit display and four programmable setpoints (with optional relay outputs) for monitoring and control applications. As an Astern-Ahead-RPM tachometer, the bargraph is centered and can show any range of -/+ (Astern / Ahead) values on a customizable faceplate. RPM value (scalable from -1999 to 9999) is optionally shown in the 4-digit display. Nearly any VDC, VAC, or mA current input signal can be accommodated. The bargraph colors can be set to red, green, or orange for either range and center. The 4-digit display can be red or green. Brightness can be reduced by half with a simple switch input.

Setpoints and relay closures can be used to alarm the user and/or trigger other equipment when certain RPM values are exceeded, e.g., say the maximum desired RPM is 135 but can be set up to 150, then a setpoint can be set up to change the bargraph color to red if RPM exceeds 135 (and relay can also be triggered at that time). Setpoints can also be used to show throttle position (throttle provides an input signal to the meter) on the tricolor bargraph including center deadband (e.g., green), changing color when the throttle is moved into the Astern (e.g., orange) or Ahead (e.g., red) zones (or center deadband is green and Astern/Ahead are orange, leaving red for RPM alarm signaling via setpoint). Relays can replace microswitch signaling to the control room for Astern and Ahead activation. The throttle position can be communicated via analog output (VDC or 4-20mA) to engine control.

Other measurement and control options are possible. Contact Texmate, Inc. to discuss your application!
