Laurel offers broad range of standard and custom-designed modules, character to graphic, COB, COG and TAB, and various backlighting systems. The applications range from instruments, process control, consumer, medical, POS to communications. View Details

The design of the Laureate™ Series is modular for maximum flexibility at minimum cost. The base configuration for a panel meter or counter consists of a main module (with computer and plug-in display boards), a power supply board, and a signal conditioner board. Optional plug-in boards include an isolated setpoint controller board, an isolated analog output board, and an isolated digital interface board. Modular design and a choice of plug-in options allow the Laureate to be customized for a broad range of applications from simple monitoring to control and computer interface. There can be up to five plug-in boards in a 1/8 DIN Laureate.

The main module (with computer and display boards) defines the Laureate series (DPM, weight meter, counter, or remote display), version (standard or extended), and LED display color (red or green). The number of digits is 5 for DPMs or 6 for counters, weight meters and remote displays. LED digits are 14.2 mm (0.56") high.

Laureate meters and counters are shipped by distributors fully configured, calibrated, and ready to run. All ranges of Laureate DC, AC and temperature meters are calibrated at the factory, with calibration factors stored in EEPROM. This allows different ranges to be selected via plug-in jumpers, with no need to recalibrate the meter for each new range. Programming can be from the front panel or by using powerful and easy-to-use Laureate Instrument Setup Software, which can be downloaded at no charge from our Software Download Page. This software can simplify setup whether the PC is connected to the instrument or not. Absolute calibration of Laureate panel meters requires temporary connection to an external calibrator and to a PC running Instrument Setup Software. System-level scale and offset calibration can also be from the front panel to produce specified readings from known signals, such as 4-20 mA = 0.00% to 100.00%.

Datalogging Software is not required for use of Laureate products with a PC. Most people use the Modbus protocol or the simpler Laurel ASCII protocol to communicate directly and read and write memory addresses, as specified in Laurel"s Modbus Communications Manual and ASCII Serial Communications Manual. Reading an writing memory addresses with custom software provides maximum speed and flexibility.

Exceptional accuracy and high read rate with five digital voltmeter ranges from 200.00 mV to ±300.0 V and four digital ammeter ranges from ±2.0000 mA to ±5.000 A, all factory pre-calibrated. Shipped ready to run.

Five AC RMS voltmeter ranges to 200.00 mV to 600.0 V and four AC RMS ammeter ranges from 2.0000 mA to 5.000 A, all factory pre-calibrated. 0.1% accuracy. Takes 5-digit readings in one AC line cycle. Shipped ready to run.

Factory calibrated for five jumper selectable resistance ranges from 20Ω to 200 kΩ. Exceptional accuracy of ±0.01% of full scale. In the 20-ohm range, resolution is 1 milliohm, making the meter suitable for contact resistance measurements. Custom curve linearization allows use with transducers whose output is a changine resistance. 3 or 4 wire connection eliminates lead resistance effects.

All capabilities of the Laureate process meter, plus custom curve linearization. Setup is easy using an external PC and linearizing software furnished by Laurel. For example, display liquid volume in irregularly shaped tanks, use with non-linear transducers, or extend the working range of nominally linear transducers.

Manufactured and Modular Homes are the most affordable option to realize your dream of building a Custom Home. Our team at Marty Wright Home Sales in Laurel Hill, North Carolina will be able to explain the benefits of buying your new home that was built in a factory. Using the same quality materials as site built homes and being built to the Housing and Urban development or the State code regulations. Your new home will be Energy Efficient, Strong, and built to last a lifetime. All of this at a much lower cost than building your new home on site. Call Marty Wright Home Sales to find out more!
