Line voltage thermostats typically have heavier contacts to handle higher current loads, often found in electric heating systems. These thermostats commonly use bimetallic sensing elements, which expand and contract with temperature changes to control the heating system. Some models may also incorporate Mercury switches or electronic sensors for improved accuracy and reliability.
for temperature sensing i will suggest a RTD or A THermocouple. for temperature sensing i will suggest a RTD or A THermocouple.
A phase sensing relay monitors all three incoming phase legs at once. With the relay the operator has the ability to set the trip points in a percentage of incoming line voltage. If the voltage in any of the monitored legs falls below the operators set point the relay will trip and take the monitored device off line. If it is a motor being protected, the auxiliary contacts on the phase sensing relay will change state and its N.C. contact will open. The motor's contactor coil is in series with this auxiliary contact so with the stoppage of current flow to the magnetic contactor's holding coil, the contactor opens cutting off the supply to the motor.
None, a TXV operates by it's sensing bulb sensing superheat of the suction line as it exits the evaporator coil.

A thermostat is a thermal sensing switch.
An oven thermostat controls the temperature inside the oven by turning the heating element on and off to maintain a consistent temperature. It works by sensing the temperature inside the oven and sending signals to the heating element to adjust its output accordingly.
what is meant by primery sensing element in terms of measurment and instrumentation system please give me ans
Thermostatic expansion valve consists of a thermal sensing element that regulates the flow of liquid refrigerant into an evaporator based on the temperature of the refrigerant returning from the evaporator.
Heater will not blow hot air. If the thermostat fails to close, which can happen if the sensing element binds up, the return spring breaks or a piece of rust or debris jams it open, the constant flow of coolant through the thermostat will prevent the engine from reaching normal operating temperature. This can cause poor driveability in cold weather, a sharp increase in fuel consumption, little or no heater output, and accelerated blowby and ring and cylinder wear.
In a hot water heater, a thermostat regulates the heat
A thermostat regulates heating and cooling in a home by sensing the temperature and comparing it to the desired temperature set by the user. When the temperature is too high, the thermostat signals the heating system to turn on. When the temperature is too low, the thermostat signals the cooling system to turn on. This process helps maintain a comfortable temperature in the home.
Thermostats operate in a way so as to control (through their extensions) temperature about a selected setpoint. Some are fixed and some can have the setpoints selected. There must be some "sensor" in the device that will react to changes in temperature. The response of the "sensor" is used to direct intervention to affect control of the temperature. Wikipedia has a good post on the different types of thermostat and how they work. A link is provided.
An ice box thermostat works by sensing the temperature inside the ice box and regulating the flow of coolant to maintain a desired temperature. When the temperature rises above the set point, the thermostat signals the cooling system to turn on and lower the temperature. Once the set temperature is reached, the thermostat switches off the cooling system.
A thermostat controls the temperature of an air conditioner by sensing the current temperature in a room and comparing it to the desired temperature set by the user. When the room temperature is higher than the desired temperature, the thermostat signals the air conditioner to turn on and cool the room. Once the room reaches the desired temperature, the thermostat signals the air conditioner to turn off.
The function of a gas water heater thermostat is to control the temperature of the water in the heater. It does this by sensing the temperature of the water and adjusting the gas flow to the burner to heat the water to the desired temperature.
A sensing element diaphragm is a thin, flexible material used in pressure sensors to respond to changes in pressure by deflecting. It converts pressure exerted on it into a mechanical displacement that can then be measured and converted into an electrical signal for further processing. The diaphragm's design and material properties play a crucial role in the sensor's accuracy and response characteristics.
