Model 2TC Integral Gauge
Solon Model 2TC Integral Gauge
Intrinsic Gauge Design
Series 2TC density switches are compact temperature compensated pressure switches available with two, three or four SPDT electric switches. This compact unit is designed for use in all high voltage circuit breakers applications. It is particularly useful when monitoring individual phases in order to reduce plumbing connections and consequently reducing the number of potential leak points. Bi-metal components provide temperature compensation to the switching
and gauge mechanisms over a wide temperature range. The unit has few moving parts which adds to its accuracy and reliability. The compact size of the unit allows easy and convenient mounting in any orientation. All intrinsic temperature compensated switches must be mounted so that they change temperature at approximately the same rate as the gas.
The modular design of the 2TC series allows Solon to work with customer's applications to achieve a reliable and economical solution to density monitoring. Solon's engineers are always available to help customers with a flexible approach toward new applications. The 2TC is available with an optional integral density gauge. This feature provides clear, visual indication of the gas density relative to the breaker fill pressure and set points.
