• Tactile Sensing

    The detection and measurement of the spatial distribution of forces perpendicular to a sensing array, and the subsequent interpretation of the spatial information. A tactile-sensing array is a co-ordinated group of Sensor Elements.

  • Temperature Coefficient of Full-Scale Span

    The percent of change in full scale span per unit change in temperature relative to the full-scale span at a specified temperature.

  • Temperature Coefficient of Resistance

    The percent change in the DC input impedance, per unit change in temperature relative to the DC input impedance at a specified temperature.

  • Temperature compensation

    Correction for the influence of temperature on a measurement.

  • Temperature Error

    The maximum change in output, at an input pressure, within the specified range resulting from a change in temperature.

  • Terminal Based Linearity (TBL)

    or end point linearity is a method of defining linearity. The maximum deviation of any data point on a transducer output curve from a straight line drawn between the end data points on that output curve. TBL is approximately twice the magnitude of Best-Fit Straight Line (BFSL).

  • Thermal Coefficient of Resistance (TCR)

    The deviation in Input Impedance due to changes in temperature over the specified temperature range, typically expressed as a ratio of the Input Impedance at Reference Temperature.

  • Thermal Coefficient of Span (TCS)

    The Thermal Effect on Span expressed as an amount of Span change occurring over a specified temperature change (e.g. TCS in %FSS/25 ºC gives the amount of Span change which occurs for a 25 ºC

  • Thermal Coefficient Offset/ Thermal Offset Shift (TCO)

    The Thermal Effect on Offset expressed as an amount of Offset change occurring over a specified temperature change (e.g. TCO in %FSS/25 ºC gives the amount of Offset change which occurs for a 25 ºC change in temperature).

  • Thermal Effect on Offset

    The maximum deviation in Offset due to changes in temperature over the Compensated Temperature Range, relative to Offset measured at Reference Temperature.

  • Thermal Effect on Span

    The maximum deviation in Full Scale Span due to changes in temperature over the Compensated Temperature Range, relative to Full Scale Span measured at Reference Temperature.

  • Thermal Hysteresis

    The maximum difference between output readings when the same temperature is reached consecutively, under the same operating conditions, with temperature approaching from opposite directions within the specified temperature range.

  • Thick Film

    Technology using screened on pastes to form conductor, resistor, thermistors, and insulator patterns; screened onto the substrate (usually ceramic) and cured by firing at elevated temperatures.

  • Thin Film

    A technology using vacuum deposition of the conductors and dielectric materials onto a substrate (frequently silicon) to form an electrical circuit.

  • Tolerance

    The maximum allowable deviation from a specified standard, as the range of variation permitted, expressed in actual values, or more often as a percentage of the nominal value.

  • Total Error Band (TEB)

    The maximum deviation in output from the Ideal Transfer Function over the entire Compensated Temperature and Pressure Range. Includes all errors due to: Offset, Full Scale Span, Pressure Non-Linearity, Pressure Hysteresis, Non-Repeatability, Thermal Effect on Offset, Thermal Effect on Span and Thermal Hysteresis.

  • Total Flow

    is the flow rate integrated over a time interval.

  • Total Pressure

    (also called stagnation pressure or ram pressure) is the vector sum of the static pressure and impact pressure.

  • Transducer

    A device or medium that converts energy from one form to another. The term is generally applied to devices that take physical phenomenon pressure, humidity, temperature, flow, etc., and convert it to an electrical signal.

  • Transfer Function

    The equation which defines the output of the product as a function of pressure over the Operating Pressure and Temperature Ranges.

  • Transmitter

    A device specifically designed to enhance communication of information from one location to another. A Pressure Transmitter is a device with a 4-20mA output specified.
