NIST traceability

The MeriamLs pocket sized M1500 analog or digital pressure transmitter is an ideal choice for meeting the full range measurement requirements from 10 "H20 to 3000 PSI. Output options include digital formats (RS-232, RS-485, and USB) or similar forms (milliampere or VDC). Choose from differential pressure (dry/dry or wet/wet), gauge pressure, composite pressure, or absolute pressure varieties, as detailed in the table below.

Considering all the effects including linearity, repeatability, hysteresis, and temperature changes from minus 20 degrees Celsius to plus 20 degrees Celsius (minus 4 degrees Fahrenheit to plus 122 degrees Fahrenheit), a typical NIST traceable digital accuracy is 0.025% of the full range.

M1500 transmits precise pressure test data to compatible digital output selection devices. Choosing RS-232 as the single output format or RS-485 to connect to a device network using the 255 format M1500 is done through terminal blocks or DB-9 serial ports. The USB digital communication option can also provide power to the M1500 through a high-power USB interface or a powered USB hub

The software is included in the initial setup and support process. Meriam Serial Protocol (MSP) or Meriam DLL can be used to send and receive information. The implementation guidelines can be obtained at www.meriam.com (see Resources/Application Notes section)

Analog output mode can also be used. Users can configure the M1500 output to 0 to 5 VDC or 4-20mA.

Two SPST photoelectric switches are included. The simulation unit uses a Meriam setting utility included with the USB Mini A Connector to configure the program, which supports configuration initialization, zeroing, recalibration, and other functions.

As for the requirement for a wider pressure range, the M1502, which supports digital output, contains two pressure sensors. The combination use of most AI or CI type pressure sensors is supported. Refer to the table below to understand these ranges. M1502 has RS-232, RS-485, or USB digital format output and does not provide analog output. A single software instruction returns two pressure readings. When multiple pressure measurements are required, M1502 reduces the purchase price and installation cost.

On site calibration: All M1500 transmitters can be calibrated on-site using applicable standards and Meriam facility settings.
