NOVUS just released NP785, an ultra-low differential pressure transmitter for measuring very small differential pressures in neutral and non-corrosive gaseous media. Designed for HVAC systems and industrial environment, the NP785 ensures temperature compensation for long-term stability and complies with electromagnetic compatibility standards, providing robustness and reliability in a wide range of applications.
NP785 can operate bi-directionally, providing the ability to measure differential pressure ranges from vacuum to positive pressure. The device has a linear proportional pressure output and a measuring range configurable via USB (by using the configuration software). The analog output can be set to 0-10 V or 4-20 mA, and features an RS485 port with Modbus RTU retransmission interface. Designed with ABS/PC housing for DIN Rail mounting, this transmitter has nickel connectors that accept pneumatic hoses with internal diameter of 4 or 6 mm.
It is very difficult to find processes that are not being monitored electronically nowadays. Whether to avoid human error, to meet regulatory requirements or even to reduce costs, the vast majority of companies have already dropped outdated clipboard notes and adopted data logging and monitoring equipment. In order to help choosing the most appropriate device to each process, this article discuss the characteristics of different electronic equipment for monitoring.
Fieldlogger was the chosen solution to measure temperature and vibration of lift pumps at several wastewater treatment plants in São Paulo state. With proper monitoring, it is possible to prevent problems and save on engine maintenance.
TxIsoRail-HRT and TxIsoBlock-HRT bring the robustness of NOVUS devices combined with HART® protocol certification, recognized worldwide as an industry communication standard for smart field devices.
The pressure measurement procedure is widely widespread within industrial processes and the reliability of these measurements is related with trade, quality, health and safety issues. In this way, a wrong measurement can create problems in the quality of the industrial process and even fatal accidents. In this article, you will find some definitions and the importance of metrology within the industry.
DigiRail Connect can be used as a slave device in Modbus RTU networks that have RS485 interface or as a server device in Modbus TCP networks that have Ethernet.
