Meriam M1500-DN0200-03-1-01 Transmitter

Digital output options for the M1500 deliver accurate pressure measure- ment to compatible receiving devices. Choose RS-232 single point or RS-485 for networks up to 255 devices. M1500 connections are made via terminal block or DB-9 serial port. The USB digital communication option also powers the M1500 via high power USB ports or powered USB hubs.

Software is included for initial setup and support. Meriam Serial Protocol (MSP) or Meriam DLL can be used to send and receive information. Implementation Guides are available at www.meriam.com (see Resources / Application Notes).

Analog output models are also available. Output accuracy is typically ±0.035% of F.S. The user may configure the M1500 for 0 – 5 VDC or 4 – 20 mA output. Two SPST opto switches are included. Analog units are configured using a USB Mini A Connector and the included Meriam Setup Utility. The utility supports initial configuration, zeroing, recalibration and other functions.

For wider pressure range requirements, model M1502 with digital output incorporates two pressure sensors. Most combinations of AI or CI type pressure sensors are supported. See the table below for available ranges. M1502 is available with RS-232, RS-485 or USB digital outputs – not available with analog output. A single software command returns both pressure readings. The M1502 reduces purchase price and installation costs when multiple pressure measurements are needed.
 

Field Recalibration

All M1500 transmitters can be recalibrated in the field using suitable reference standards and the Meriam setup utility.

EPI / THE EMBEDDED PRESSURE INSTRUMENT

The EPI™ is a fully compensated instrument capable of measuring applied pressures and providing an accurate and fully characterized digital output. The Meriam M1500 Pressure Transmitter, as well as other pressure products from Meriam, are powered by the EPI™. This ensures you are getting a highly-accurate device capable of ±0.025% FS including all effects of linearity, hysteresis, repeatability and temperature over specified operating temperature range. NIST traceable certification is standard. The EPI™ provides true 14 samples per second data rate of accurate pressure readings.
