Hermetic/Oil Filled Transformer Temperature Controllers

Tecsystem has a variety of electronic temperature controllers specifically designed for wet applications, primarily Oil Filled Transformers and Hermetic Transformers, but also diesel generators, bearings, exhaust gas, lubricating oil and coolant. The Tecsystem name represents high quality, advanced technology & research, and unrivaled service.

BB211-RS485 & TPL503

Then new BB211-RS485 combined with the TPL503 sensor represents a new era for the protection of hermetic oil-filled transformers. The TPL503 replaces the aging electromechancial control devices. Installed directly on the transformer the TPL503 is able to monitor Temperature, Pressure and Level of the oil. Your hermetic oil filled transformer will never be alone again! The BB211-RS485 controller has 2 alarm output relays (ALARM-TRIP) and 1 alarm relay for signaling sensor faults or other self-diagnostic faults. It also has 1 alarm relay for fan control, and powers the TPL503 sensor. The BB211-RS485 also contains an RS485 Modbus RTU serial output for those who want more information delivered to a remote location.

MM453 - up to 24 inputs

The MM453 temperature controller is designed for measuring the temperature of diesel generators and biogas as well as monitoring bearings, exhaust gas, lubricating oil and coolant. The MM453 is highly configurable with up to 24 temperature inputs using any of our RTD PT100, PT1000 or TCK thermocouple. 5 standard output relays with the option to add a 4-20mA analog and/or a RS485 digital output give you the flexibility you need to monitor temperature across your operation.

T412 - 1 input

The T412 is a great choice when a single hot spot needs to be monitored. It has 1 input that can be used with an RTD like our PT100. It has two alarm relays for different temperature thresholds and one fault relay for signaling sensor faults or other self-diagnostic faults.
