产品描述

Mil-Ram’s Multi-Process Wireless Telemetry System utilizes  902928 MHz frequency hopping spread spectrum technology to link any field-installed 4-20mA transmitter  with  new  or  existing  control systems (controllers, PLC’s, etc.) accepting standard 4-20mA inputs. One or more radio transmitters (MPT900T) are installed in the field and each can accommodate up to eight 4-20mA transmitter inputs. Each field radio transmitter  (designed for hazardous or ordinary locations) converts the 4-20mA signals (16-bit, high resolution A/D conversion) into wireless data (sensor readings) and sends the data packets  to  a  radio  receiver (MPT900R)  located  at  the  control system. This receiver converts the wireless data back to discrete 420mA analog outputs for direct connection to control system. The Mil-Ram  system  simply  and  reliably  replaces  the  wire  that traditionally  interconnects  the 4-20mA  transmitter  and  control system. A Mil-Ram wireless installation provides tremendous cost savings as installation costs associated with hard-wired systems can greatly  exceed  the cost of the equipment. The Mil-Ram  MultiProcess Wireless Telemetry System is practical and cost effective for small systems consisting of only a few monitoring points up to much larger systems utilizing several hundred remote points. Distances between the field installed  4-20mA transmitter and control system can  exceed 20  miles  line-of-sight. Actual  distances  depend  on antenna selection and specific factors in the environment (buildings, structures, terrain, etc.). Signal repeaters (MPT900RP) are available to extend distances especially in areas where line-of-sight installation is not possible.
