Hello Забери билет от Гос.Лото,
This month we feature alarm trips and essential devices that help to ensure processes are kept operating within set parameters. Additionally, we cover the SPA2IS alarm trip and address a differential temperature application in a facility utilizing intrinsic safety. A nitrogen blanketing application shows how a customer used a SPA2 to help ensure the safety of workers, and we provide a look at our catalog of alarm trips.
Heater Differential Temperature Monitoring And Alarming Using Associated IS
A facility needed to measure inlet and outlet temperature of a process heater using existing three-wire RTDs and provide a 4-20mA process variable signal, representing the differential temperature across the heater, to a local alarm trip for heater protection and share that differential temperature signal with the Basic Process Control System (BPCS). In addition, the measurements are in a hazardous area and plant standards require the use of a certified IS system.
SPA2IS Reduces Installation and Maintenance Costs
The newest member of Moore Industries' family of Limit Alarm Trips and Switches, the SPA2IS is a combination alarm trip and temperature transmitter solution that includes built-in intrinsically-safe field connections for current/voltage, resistance temperature detectors (RTDs), and thermocouples. It significantly reduces wiring, installation, and maintenance costs for facilities that employ intrinsic safety methods of protection.
Nitrogen Blanketing Application With SPA2 Alarm Trip
Nitrogen is often used for packaging purposes and other processes inside manufacturing facilities. The level of oxygen inside of the manufacturing area where nitrogen is used must be monitored because the same nitrogen used for oxygen displacement to preserve the valuable contents of a vessel could become deadly to the employees working in the room. The Moore Industries SPA2 Programmable Limit Alarm Trip can help avoid a potentially dangerous escape of nitrogen gas into a manufacturing facility.
Alarm Trips and Trip Amplifiers
Alarm Trips and Trip Amplifiers provide on/off control, warn of trouble, or provide emergency shutdown with one or more programmable alarm (relay) outputs when a monitored process signal falls outside of a selected high and/or low limit.
