Abstract
A leakage checking device for a steam trap is provided to reduce installation time and costs without wiring because leakage of the steam trap is wirelessly checked. A leakage checking device for a steam trap comprises a temperature sensor, a temperature controller, a transmitter, and a receiver. The temperature sensor is arranged at a condensed water outlet of the steam trap for detecting temperature at the outlet. The temperature controller is arranged at the condensed water outlet of the steam trap and sets required sensing temperature of the temperature sensor. The transmitter transmits signals wirelessly under set temperature. The receiver receives the signals of the transmitter in forms of words and numbers. When the reception of the electric wave is unstable due to locating the transmitter and the receiver far away, a transponder assists the reception of the electric wave. According to need, the device is composed of the temperature sensor, the temperature controller and an alarm device, or just composed of a bimetal thermometer. The leakage of the steam trap can be rapidly checked, thereby saving energy, shortening installation time of check device for the leakage of the steam trap, and saving installation cost and maintenance cost.
