    4Rosemoun t RTD Dif ferent iat ion

    Type of element Platinum Rosemount has externally

    wound RTD for faster response time

    Thin-film has slightly faster response time thanwirewound

    Element packaging Rosemount RTDs are packed in aluminum oxide to

    provide optimum thermal conduction within the sheath

    Grounded thermocouples are twice as fast as ungrounded Sheath thickness and material

    Rosemount uses 316SST and Inconel (for hightemperatures) for sheath; both are very good thermalconductors

    Sensor Response Time Improved

    (T) Lagging length

    This is the lagging length plus a

    fixed allowance of 1.

    This is the additional length

    between the thread allowance

    and hex allowance to

    accommodate piping insulation.

    (U) Immersion length into process

    For best accuracy, this length should be long

    enough to permit the bottom one inch of the

    thermowell to be into the process.

    Typically, the sensor is immersed up to one-half

    the diameter of the pipe.

    (E) Extension fitting length

    This dimension describes the effect of

    This is critical if it is necessary to keep

    2. If they were using a

    series 68 sensor assemblywhat length would L and T

    be?

    4. How long is the thermowell they are using?

    The IEC 751 standard curve (programmed into all our

    transmitters) describes an IDEAL Resistance vs Temperature

    relationship for Pt100 a385 RTDs.

    The goal is to find out what the real RTDcurve looks like, and reprogram thetransmitter to use the real curve!

    Every RTD is slightly

    different - theyre not ideal!

    The four coefficients R0,, a, b, d are characteristic of each individual sensorand may be determined for each sensor by calibration at four different

    temperature points and it is these that appear on the sensor wired-on label

    when V-options are specified. The temperatures chosen for calibration are

    usually 0, 100 C, and at least one point below zero and one above 100 C.
