Moore Industries Spotlight: Alarms

Moore Industries Spotlight: Alarms

Moore Industries has been designing and manufacturing alarms since 1968 (read our recent blog on our presence in the process instrumentation industry: Moore Industries: A History of Innovation and Safety). Our alarms have evolved from simple high/low logic devices to highly flexible PC-programmable devices extending into IEC 61508 Functional Safety and Intrinsically-Safe (IS) methods of protection. To learn about Moore Industries’ alarm products, visit our Limit Alarm Trips and Switches Product Information Page.

The SPA2 Automates a Sewage Treatment Sludge Pump Application

The SPA2 Automates a Sewage Treatment Sludge Pump Application

A sewage treatment plant needed to automate the start-stop of a large pump/grinder motor. The existing application used a tank level meter to signal the start-stop of the motor. However human intervention was frequently required to manually override the motor stop mechanism to allow it to continue to operate after the tank was emptied to assure the grinder portion was clear of old debris that would cause a possible stall on the next start. See how the SPA2 helped solve this problem.

EHELP: Alarm Tank Level Changes with the SPA2

EHELP: Alarm Tank Level Changes with the SPA2
Q: I want to install a 4-20mA pressure transducer that shows the tank level with an alarm to alert if it is outside the controlled level. With the same signal I want to display the level, alert of level loss, and shut down the pumps if the level reaches a critical point.

New SPA2IS Programmable Alarm Trip with Intrinsically-Safe (IS) Field Connections Reduces Installation and Maintenance Costs

New SPA2IS Programmable Alarm Trip with Intrinsically-Safe (IS) Field Connections Reduces Installation and Maintenance Costs

Moore Industries has released the new SPA2IS programmable alarm trips with built-in intrinsically-safe (IS) field connections. Now customers in the chemical, petrochemical, oil & gas extraction & refining and pharmaceutical industries that monitor, control, and measure signals in hazardous areas have an alarm solution that significantly reduces wiring, 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 thermocouple.

New Configuration Options Added to STA

New Configuration Options Added to STA
In response to customer feedback, the STA Safety Trip Alarm has been updated to provide more flexibility in handling input faults. This allows for spurious alarm to be minimized and for alarms to be cleared with power cycling or needing physical access to the unit.
