The MT300, from Brampton, Ont.-based Mod-Tronic Instruments, is an important device that helps companies safeguard expensive transformers and machinery by monitoring them. It consists of a three-channel transformer temperature monitor and alarm system that controls three relay outputs based on user-programmable set points.
The MT300 features an improved measurement range of -50 to 300 degrees C, and universal inputs of either 100Ω or 1000Ω Platinum RTDs or Types E or K thermocouples. The microprocessor-based design maintains accuracy over a wide range of temperatures and conducts regular self-checks to ensure correct operation. Additionally, one of the relay outputs is specifically designed to control a cooling fan with a 30-amp rating. The user-configurable fan exercise option extends the fan life and reduces bearing lock-up. The monitor is easily configured via MODBUS over a USB connection to a PC or MODBUS/RS-485 using the included PC software that also provides data logging.
The MT300’s other key features include:
- A large, dimmable seven-digit LED display that allows easy programming and visibility at various distances and lighting conditions;
- A dual password design that allows certain users to have full configuration access and others, set points only;
- Non-volatile memory storage of per-channel min/max temperatures for recall in the event of power-loss; and
- Electrically isolated 4-20mA output signal for connection to PLCs or remote displays.
The universal temperature monitor also has UL/cUL recognition and a three-year warranty. In addition, it’s capable of utilizing any combination of the supported sensor types.
The MT300 is designed for dry-type transformer monitoring and protection. However, it can also be used in pumps, compressors and motors. For more information on this product, contact Mod-Tronic Instruments.
