Thermo Scientific™ Motion Monitor Systems measure the speed of rotating machinery and detect under-speed, over-speed and zero-speed conditions. They detect any deviance from your acceptable operating parameters, allowing you to troubleshoot system upsets or failures. This leads to reduced downtime and increased productivity, ultimately adding to your bottom line.
Thermo Scientific™ Motion Monitor Systems offer a choice of versatile and reliable packages for monitoring speed conditions on various types of machinery and systems by sensing the speed variations of rotating parts. The Motion Monitor can detect under-speed, over-speed, and zero-speed conditions as well as transmit a proportional speed signal. You can choose from mechanically coupled (shaft-driven) or non-contacting proximity type sensors to satisfy your particular application requirements and design preferences.
The control system for these unique systems are housed in separate NEMA 4X enclosures which can be mounted near the sensing components or, for convenience and accessibility, up to 610 m (2,000 ft) from the sensor.
Thermo Scientific Ramsey Model 60-200 Motion Monitor Control
The Ramsey™ Model 60-200 programmable motion monitor control is a flexible microprocessor-based controller that can be used with any Thermo Scientific sensor and, in some cases, with compatible pulse output sensors from other sources.
All alarm functions, delays and operating parameters are entered via a simple threebutton keyboard. There are no potentiometers to adjust. A four-digit, seven-segment display shows the current speed as a percentage relative to a user-programmed reference speed. It also displays various parameters and setup values when the control is in its setup mode. Finally, the display shows an error code if any problems occur. This helps the operator to troubleshoot system failures or other difficultie
Detailed programming instructions are contained in the system manual and a quick reference programming guide is displayed on a label inside of the control’s enclosure cover. Depending on the model used, one or two DPDT outputs are available to transfer information about the monitored conditions from the monitor to remote alarm displays or control functions. Also available is a 0 to 2 VDC output or an optional 0-20 mA/4-20 mA signal proportional to the rotational speed of the monitored shaft.
The Ramsey Model 60-200 is available in two versions, a single channel or a dual channel. The alarm on a single channel model can be set at 1% increments over a range of 0% to 160% of the reference speed to provide an under-speed or an over-speed alarm. The dual channel model has two independent alarms, each adjustable between 0% to 160%.
Other programmable setup features include: start-up delay, alarm delay, reset mode, start-up delay initiation and alarm clearing.
Thermo Scientific Ramsey Model 60-22 Motion Monitor System
This system uses a Ramsey Model 60-200 controller and a Ramsey Model 60-220 non-contacting proximity type sensor used for measuring shaft rotation. It is available with either the single or dual channel controller and in either high speed or low speed. The sensors include an LED that indicates pulse outputs which simplifies system setup and troubleshooting. All sensors include 6 m (20 ft) of lead wire and a mounting bracket.
The Ramsey Model 60-220 sensor may be mounted in Class I or II, Division 2 hazardous areas if the wiring is run in approved conduit. For use in Class I or II, Division 1 areas, an intrinsic safety barrier must be incorporated into the signal leads. The Ramsey Model 60-200 control must always be located in a non-hazardous area.
Options include: a stainless-steel sensor, intrinsic safety barriers, conduit connectors, several target options with appropriate hardware, and an analog current output to transmit shaft speed.
Thermo Scientific Ramsey Model 60-24 Motion Monitor System e
This system uses a Ramsey Model 60-200 controller and a Ramsey Model 60-240 direct coupled, shaft-driven sensor for measuring shaft rotation speed. It is available with either the single or dual channel controller and in either high speed or low speed. A very low speed version is available capable of very sensitive operation at very low shaft speeds (less than 0.025 RPM). All systems include a conduit type connector and 1.5 m (5 ft) lead wire.
The Ramsey Model 60-240 sensors are approved for Class II combustible dust hazardous areas. If used in a Class I hazardous area, an intrinsic safety barrier must be incorporated into the signal leads. The Ramsey Model 60-200 control must always be located in a non-hazardous area.
Options include two versions of speed sensor mounting kits, intrinsic safety barriers, and an analog current output to transmit shaft speed.
