The Laureate™ 1/8 DIN Panel Meters for RTD'S
is factory calibrated for four Resistance Temperature Detector (RTD) types: 100-ohm platinum (Pt100) with DIN alpha of 0.00385, 100-ohm platinum (Pt100) with ANSI alpha of 0.003902, 10-ohm copper with alpha of 0.00427, and 120-ohm nickel with alpha of 0.00672. The entire span of each RTD type is presented in a single range. The RTD type, unit of measure (°C or °F) and resolution (1°, 0.1° or 0.01°) are selectable from the front panel or via the panel meter's serial interface. Display in Kelvin or Rankin is selected by offsetting the Celsius or Fahrenheit ranges. Typical accuracy is better than ±0.1°C (±0.2°F).RTD connections can be via 2, 3 or 4 wires. With 3 or 4-wire connections, the meter automatically compensates for changes in lead resistance to the sensor. With 2-wire connection, the panel meters can measure and then subtract the lead wire resistance.
All RTD types are factory-calibrated, with calibration factors for each range securely stored in an onboard EEPROM. These factors can be scaled via software to accommodate external shunts, enabling field replacement of signal conditioner boards without necessitating recalibration of the associated panel meters. For optimal accuracy, factory recalibration is recommended annually. All Laurel Electronics instruments undergo factory calibration using the industry-leading Fluke calibrators, which are recalibrated yearly and certified traceable to national standards, ensuring the highest level of precision and reliability.
Laureate Panel Meters are easily programmed with Laurel’s free Instrument Setup Software, downloadable from our website and compatible with Windows PCs, requiring a data interface board for setup.
High read rate of up to 50 or 60 conversions per second, the Laureate™ Panel Meters use Concurrent Slope (US Pat. 5,262,780) analog-to-digital conversion to integrate signals over a full power line cycle (50 Hz or 60 Hz). This read rate enables peak and valley capture, real-time computer interfacing, and control applications. Peak and valley values are automatically captured and can be viewed using Laurel’s free Instrument Setup Software (compatible with Windows PCs) or transmitted as serial data.
Digital signal filtering modes can be selected to ensure stable readings in electrically noisy environments.
- An unfiltered selection provides true peak and valley readings and aids in control applications.
- A batch average filter selection averages each 16 conversions.
- An adaptive moving average filter selection provides a choice of 8 time constants from 80 ms to 9.6 seconds. When a significant change in signal level occurs, the filter adapts by briefly switching to the shortest time to follow the change, then reverts back to its selected time constant. An Auto setting selects the time constant selection based on signal noise.
Two tare functions: auto-tare and manual tare. In auto-tare, an input line is grounded by an external pushbutton. In manual tare, the tare value can be entered manually via a control input pushbutton or using Laurel's free Instrument Setup Software.
Peak and valley values are automatically captured. These may be displayed via a front panel pushbutton command or control signal at the rear connector, or be transmitted as serial data.
Two rear panel control Inputs (CMOS/TTL levels, logic 0 = tied to digital ground, logic 1 = open) or dry contacts that can be set to control / activate 14 meter commands.
RTD Connections with Excitation & Lead Compensation
RTD hookup can be via 2, 3 or 4 wires to the J5 connector. The panel meters apply an excitation current of 256 µA (Pt100 and Ni120) or 5 mA (Cu10).
 |
In 4-wire hookup, different pairs of leads are used to apply the excitation current and sense the voltage drop across the RTD for ratiometric operation, so that the IR drop across the excitation leads is not a factor. |
 |
In 3-wire hookup, the panel meters sense the combined voltage drop across the RTD plus two excitation leads. It also senses the voltage drop across one excitation lead, and then subtracts twice this voltage from the combined total. This technique effectively subtracts all lead resistance and compensates for ambient temperature changes if the two excitation leads are identical. |
 |
In 2-wire hookup, the panel meters sense the combined voltage drop across the RTD and both lead wires. The voltage drop across the lead wires can be measured by shorting out the RTD during meter setup, and this voltage is then automatically subtracted from the combined total. However, changing resistance of the lead wires due to ambient temperature changes will not be compensated. |

Dimensioned CAD assembly drawings in EPRT, STEP, x_t. dwg, pdf file formats: Laureate-meter-case.zip (zipping prevents browser from opening CAD files as text files).
Panel Mounting
Slide the meter into a 45 x 92 mm 1/8 DIN panel cutout. Ensure that the provided gasket is in place between the front of the panel and the back of the meter bezel.
The meter is secured by two pawls, each held by a screw, as illustrated. Turning each screw counterclockwise extends the pawl outward from the case and behind the panel. Turning each screw clockwise further tightens it against the panel to secure the meter.
Turning each screw counterclockwise loosens the pawl and retracts it into its well. This position allows installed meter to be removed from their panel, or new meters to be installed in a panel. Do not remove the screws from their pawls. Doing so would cause the screw and pawl to fall off and likely get lost. Do not overtighten so as not to damage the plastic parts.
Operation as a 4-20 mA Transmitter
With the optional analog output board, Laureate RTD temperature meters can serve as superb, isolated 4-20 mA transmitters. The analog output is scaled to the display, which is linearized to °C or °F and is exceptionally accurate. The analog output further tracks the high read rate of the meter, at up to 60 readings per second at 60 Hz power. Fast update rates are beneficial in many closed-loop and PID control applications.
 |
 |
Operation as a Fast Controller
By using the optional dual contact relay or dual solid state relay output options, Laureate temperature meters can monitor processes and provide alarms or shutoffs when these processes exceed normal limits. A band deviation operating mode can be selected for each relay, where an alarm is generated whenever the reading is a selected number of counts above or below the setpoint. Relay operation can be selected as latching or non-latching. When an alarm or shutdown condition is reached, a latched output will remain in the alarm condition until it is reset by a front panel pushbutton, via the serial interface, or via the rear connector.
