Warrick Conductivity Controls | Gems Sensors

Warrick® Conductivity level control systems rely on the liquid level sensing capability of probes (electrodes) that are housed inside fittings designed to accommodate one or more probes. The concept is simple: take advantage of a liquid's conductive properties to complete a circuit and cause a control relay to actuate. These single- or multi-point sensors have no moving parts and the

Water Handbook - Boiler Blowdown Control | SUEZ

Blowdown control; Boiler blowdown is the removal of water from a boiler. Its purpose is to control boiler water parameters within prescribed limits to minimize scale, corrosion, carryover, and other specific problems. Blowdown is also used to remove suspended solids present in the system.

Measuring Electrical Conductivity - control

Thus, the measure of a water samples electrical conductivity is a function of its ionic impurity concentration. Conductivity is therefore an important analytical measurement for certain water purity applications, such as the treatment of boiler feedwater, and the preparation of high-purity water used for semiconductor manufacturing.

Radiator (heating) - Wikipedia

Radiators and convectors are heat exchangers designed to transfer thermal energy from one medium to another for the purpose of space heating.. Denison Olmsted of New Haven, Connecticut, appears to have been the earliest person to use the term 'radiator' to mean a heating appliance in an 1834 patent for a stove with a heat exchanger which then radiated heat.

Heating boiler aquastat control diagnosis, troubleshooting

Oil Burner Short Cycling Traced to Poor Aquastat Temperature Sensor Contact: use the heat conductive grease. We have observed occasional short or sporadic oil burner (and some gas burner) "on" cycles that were hard to track down. Technicians even replaced aquastats on a test system we've been monitoring, only to have the problem continue.
