摘要： A heat trace system heats (or maintains the temperature of) vessels of a piping system. Heat trace cables are connected to power control devices in respective wireless modules such that when the power control device in a wireless module is on, the heat trace cable connected to that wireless module conducts current, and thereby heats the vessel contacting the heat trace cable. The wireless module receives control commands for controlling its power control device wirelessly from the main power distribution and control system via a wireless communication network. A wireless module can include a sensor, where the wireless module report backs conditions sensed by the sensor to the main power distribution and control system via the wireless network. The main power distribution and control system can use that information in its control loops to control the switching of the power control devices in the wireless modules, to thereby control whether the associated heat trace cable conducts current or not, to thereby control the temperature at the vessel that is heated by the heat trace cable.

摘要： Powering a sensor module of a heat trace system used for heating vessels. The sensor module may comprise a temperature sensor that measures the temperature of a vessel. A microprocessor-based controller of the heat trace system uses the sensed temperature from the sensor module to control the voltage applied to the heat trace, and thereby control the heat provided by the heat trace to the vessel. The sensor module may comprise an energy storage device that stored energy from the voltage difference across a pair of buss wires in the heat trace cable, and the stored energy is used to power the components of the sensor modules.

摘要： Heat trace system for heating vessels of a piping system comprises a main control system, a plurality of heat trace elements, and a plurality of wireless modules. Each heat trace element is adjacent to one of the vessels of the piping system and connected to an electrical power source of the main control system 16. Each of the wireless modules: (a) is connected to and powered by an associated heat trace element; (b) comprises an energy storage device connected to the associated heat trace element for storing energy from the associated heat trace element to power the wireless module; and (c) comprises an RF module for communicating wirelessly with the main control system via a wireless communication network. The stored energy in the energy storage device can be used to power components of the wireless module, even when no current is flowing in the heat trace element to which the wireless module is connected.
