Product Details
Meriam’s compact, new M1500 Digital Pressure Transmitters are ideal for pressure measurement needs from 10” H20 (pending) to 3000 PSI Full Scale. Output options include digital (RS-232, RS-485 and USB) or analog (mA or V DC). Chose from differential (dry/dry or wet/wet), gauge, compound or absolute pressure types – see info below for complete details.

Typical NIST traceable digital accuracy is ±0.025% of F.S. including all affects of  linearity, repeatability, hysteresis and temperature from -20Ί to +50Ί C (-4Ί to +122Ί F).  Digital output options for the M1500 deliver accurate pressure measurement to compatible receiving devices. Choose RS-232 single point or RS-485 for networks up to 255 devices. M1500 connections are made with a 7 position 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 Modbus RTU protocol can be used to send and receive information. Implementation Guides for MSP and Modbus RTU are available at www.meriam.com (see Resources / Application Notes).

Analog output options 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 alarm switches are included. Analog units are configured using the RS-232 terminals and the included M1500 Measurement & Configuration Software. The software supports initial configuration, zeroing, recalibration and other functions. Meriam recommends Analog starter kit PN Z9P337 for first-time buyers. 

NIST Traceable Accuracy
