Profile: Presys Instrumentos & Sistemas Ltda. specializes in instrumentation and process control. We are an ISO 9001 certified company. We manufacture control instruments and software (to be used together with the instruments). We manufacture virtual recorders, process multi-loop indicators, process dual indicator & totalizer, dual pressure indicators, process dual counters, universal process dual loop controllers, and universal smart transmitters. The virtual recorder VR-2000 software is designed to perform analog and digital recorder functions, using Presys 2000 family of microprocessed instruments & serial communication. Up to 30 instruments can be connected, achieving up to 360 measuring points and 120 recorded points. Besides recording process variables in hard disk, VR-2000 offers alarm programming to warn the operator of abnormal process conditions with acknowledgment, history, messages and printed reports of alarms. Recorded data are exported to worksheet and database formats in agreement with operator needs. This feature allows further process analysis and optimizations in worksheets from VR-2000 recorded data. The design of DMY-2030 indicator and DMY-2030-TOT indicator-totalizer is characterized by high reliability & precision, electrical noise and EMI immunity, besides well elaborated technical manual. These features make them ideal for industrial applications in instrumentation and process control. They have an extruded aluminum case and use the origin components and parts, proven by rigorous tests & specified according to the strictest worldwide norms. Indicators offer two standard universal inputs that can be 4-20mA, 1-5Vdc, 0-10Vdc, 0-55mVdc, thermocouples and RTD, also standard is the 24Vdc power supply for two-wire transmitter.
