242E Temperature/Pressure Recorder-Receiver Section 1Section 1—IntroductionGeneralThe Barton Model 242E Temperature and Pressure Recorder-Receiver is aversatile and rugged instrument designed for general temperature and pressureapplications. It records monitored temperature and pressure on a 12-inchdiameter chart. Up to four elements or bellows-type receiver elements may beused in any combination to operate up to four individual recording pens.Main ComponentsStatic Pressure SystemsThe static pressure system consists of a helical bourdon tube connected tosystem piping. The static pressure element measures the static pressure in apiping system. Elements are available for measuring pressures ranging from30 in. of vacuum (mercury) to 30,000 psi. For a list of elements and ranges,see Table 7.3—Static Pressure Elements on page 31.Thermal SystemsThe thermal systems consist of a spiral bourdon tube, a capillary, and a bulb.All parts are made of stainless steel. The bulb is fitted with a bendable extension,and the capillary is protected with stainless steel armor.Receiver BellowsThe 242E recorder may be connected to a pneumatic transmitter to record the3-15 or 6-30 psi output signal of the transmitter. The instrument may also beconnected to record the output of a pneumatic transmitter simultaneously withthe direct system pressure.Recording MechanismThe recording mechanism is a linkage and pen system that permanently recordsdata. It converts mechanical inputs from the pressure, temperature, andreceiver elements to link lines on a revolving chart. All operative parts of therecorder mechanism are made of stainless steel for a long field life. The penmount is exceptionally rugged. All lines are adjustable. Screw adjustments forzero, range, and linearity assure fast and accurate calibration.3
