Override and selective control - Control Global

Yet another use of selective control in critical control systems is to select the most reliable among multiple sensors or transmitters. For example, in critical reactor feed applications or in hostile environments (corrosive, dirty, vibrating, high-temperature), we often assure measurement reliability by using median selectors or voting systems to disregard a failed detector among three sensors.

High-pressure area - Wikipedia

High-pressure areas form due to downward motion through the troposphere, the atmospheric layer where weather occurs. Preferred areas within a synoptic flow pattern in higher levels of the troposphere are beneath the western side of troughs.. On weather maps, these areas show converging winds (), also known as convergence, near or above the level of non-divergence, which is near the 500 hPa .

I just put a new temperature gauge on front of my boiler and for an Aquastat setting of 180 for high the gauge temp goes up to 220 .I set the aquastat to 160 low and high temp reaches 200 .So it's about 40 degrees off . The aquastat is a Honeywell L8124C and probably about 15 to 20 years old .

PID Controllers - Temperature Controllers

To accurately control process temperature without extensive operator involvement, a temperature control system relies upon a controller, which accepts a temperature sensor such as a thermocouple or RTD as input. . If the temperature is below setpoint, the output will be on longer; if the temperature is too high, the output will be off longer.

Air Conditioners: Air Conditioner Operating Temperatures .

Too high air conditioning output temperatures may indicate that the system is not working properly: perhaps the coil has become blocked solid with ice. Alternatively, high A/C outlet temperatures may be occurring, or even no cooling at all, due to other problems such as a loss of refrigerant. (Don't just add refrigerant, find and fix the leak.
