MTN/3000 Manual Switching Box
- Manufacturer: Monitran
- Category: Signal converters, INSTRUMENTATION
Monitoring vibrations at critical points located in hard-to-reach areas or with high safety risks presents a logistical challenge and a danger to maintenance personnel. Taking manual measurements on cooling tower motors, high-rise fans, or machinery in confined spaces necessitates plant shutdowns or exposes the technician to hazardous conditions.
The MTN/3000 series solves this problem by allowing the permanent wiring of up to 64 sensors to a secure, centralized control point. This switching unit requires no external power supply, as it utilizes the constant current from the technician's own portable data collector. A highly reliable rotary selector on the front panel allows the operator to switch between different measurement points and capture the signal via a single BNC, TNC, or MS output connector.
Built in a robust steel enclosure (painted or stainless steel) with an IP65 protection rating, the unit is designed to withstand the harshest industrial environments. Internal connections are made via screw terminals mounted on a DIN rail, facilitating organized installation and allowing for future expansion or integration of signal conditioning for dual vibration and temperature sensors.
- Centralization of up to 64 channels measurement in a single secure location.
- Passive operation: It does not require external power. to function.
- Industrial protection IP65 with hinged door and security lock.
- Available in stainless steel (-SS) for corrosive or food environments.
Technical Frequently Asked Questions
1. What type of cabling is compatible with the box inputs?
The MTN/3000 enclosure accepts any standard accelerometer cable. The cables are inserted via watertight cable glands and terminated internally on DIN terminal blocks, ensuring a firm mechanical connection and excellent analog signal integrity.
2. Can temperature signals be monitored in addition to vibration?
Yes. Although the standard model is for vibration, there are variants (such as the MTN/3000D) specifically designed to work with dual sensors (e.g., MTN/1100T). These versions allow switching between the vibration and temperature signals for each monitored point.
3. Is it possible to add 4-20mA outputs to this unit?
Yes, the MTN/3000 series is highly modular. Signal conditioning circuits can be integrated upon request to convert readings into 4-20 mA current outputs, or digital displays can be added for direct reading of values on the front panel of the enclosure.
