Available in 1/2” NPT and 3/4” NPT process connections in brass or 316 SS.Thermal WellJam nuts provided with thermal wells.11Switch Unit – ASCO uses the term “switch unit ” to describe the electromechanical portion of a pressure or temperature switch. This is used in conjunction with a transducer unit to form a complete pressure or temperature switch.Transducer Unit – ASCO uses the term “transducer unit ” to describe that portion of a pressure or temperature switch to which a pressure or temperature is applied which converts the input signal to another form of energy to operate the switch unit.Two-Stage (Dual)– ASCO uses the term “two stage ” todescribe a pressure or temperature switch which is equivalent to two pressure or temperature switches which are independently adjustable. This switch is equivalent to two fixed deadband switches.Deadbands – The deadband is the difference between the set point and reset point readings. Deadbands are listed in the specification tables at nominal values. They are representative of the deadbands of the units at the middle of the range.The deadband values for the full range adjustable deadband switches and limited adjustable deadband switches indicate the values through which the deadband may be adjusted.Generally, as the set point is adjusted through the operating range, the deadband will vary. Normally, it will becomenarrower as the set point is towards the bottom of the range,and will become wider when the set point is towards the top of the range. The graph shown below indicates representative trends of this type of deadband variation.Temperature switch deadbands are a result of the characteris-tics of the vapor pressure curve as well as other factors.Normally, this results in a deadband which is narrower in the top third of the range than in the bottom third of the range.The values published are nominal and representative of mid-range set points.36Accuracy – The maximum deviation from the set point under specified operating condition (ambient temperature,barometric pressure, etc.).Adjustable Deadband – Refers to the capability of apressure or temperature switch to allow the deadband to be adjusted over a given range. Certain ASCO TRI-POINT switches have an adjustable deadband which can be adjusted over the total operating range of the switch.Adjustable Operating Range – The pressure or tempera-ture range of the switch within which the set point may be adjusted.Differential Pressure – The difference between twopressures. A differential pressure switch senses two pressure sources and can be adjusted to actuate on a desired difference between them.Guage Pressure – The actual reading of a typical pressure guage and is the difference between the pressure within a vessel and the atmospheric pressure surrounding it. It is normally measured in pounds per square inch (psig).Manual Reset – The switch is a semi-automatic device which operates automatically with a signal change in one direction but must be manually reset once the signal returns to its original position.Proof Pressure – A pressure which a device can besubjected to for extended periods of time without changes in its operating characteristics.Rated Overrange Temperature – A temperature which a device can be subjected to for extended periods of time without changes in its operating characteristics.Repeatability – The closeness of agreement among a number of consecutive measurements of the output for the same value of input under the same operating conditions approaching from the same direction. Repeatability isnormally specified as a percentage of the upper limit of the operating range.Example: Operating range 5-100 psig with +1%repeatability; equals +1% of 100 psig or +1 psig.Reset Point – After a pressure or temperature switch has reached its set point and operated the electrical switch, it must return to a point called the reset point before the electrical switch can return to its original position.Set Point – The pressure reading at which the electrical switch element changes contact position (it can be specified either increasing or decreasing).DefinitionsDeadbands1.5 x Catalog Value Catalog Value Half Catalog ValueBottom Mid TopPosition of Set Point in Range37These recommendations are to be used as a guide only, as service life of material is dependent on temperature, concentrations, or catalysts that may be added and other conditions which are beyond our control.Consult ASCO for specific service applications.Note:Items in black circles are standard catalog units.All others available on factory order.P - Indicates preferred construction.
