STA Aids in Functional Safety Coal Gas Extraction Application Down Under

STA Aids in Functional Safety Coal Gas Extraction Application Down Under

Moore Industries-Pacific recently sold 221 STA Safety Trip Alarms to be used in a Functional Safety coal gas extraction application in Australia. A Coal Seam Gas exploration company with hundreds of sites in Queensland has production wells with up to 10 inputs controlled locally by Remote Terminal Units (RTUs). The STA will be implemented as part of their independent Protection System with a level alarm on each wellhead separator. Larger volume production wells may need up to four separators per RTU panel.

E-HELP: Configuring the STA for Multiple Pressure Levels

E-HELP: Configuring the STA for Multiple Pressure Levels
Q: I need to use the STA Safety Trip Alarm in a hardwired panel. Is it possible to configure two different levels of alarm for each of two relays in the STA, in order to have two different trips (one for each relay)?

Universal Power Supply Added to STA

Universal Power Supply Added to STA
The STA Safety Trip Alarm datasheet and installation manuals have been updated. The new change reflects the addition of a Universal power supply to the unit. Previously, customers needed to select either a 24DC or UAC power supply. The new Universal power supply accepts any power input range between 21.6-375Vdc or 90-260Vac.

E-HELP: Using the CPA to Create a Temperature Switch

E-HELP: Using the CPA to Create a Temperature Switch
Q: I am looking for a device to create a temperature switch. I currently use a simple temperature switch with a 230°F setting, but at times the temperature of the unit goes over 400°F briefly and destroys the switch. I need to be able to hook a thermocouple up to the device and program a setpoint (with no display required) and have a set of dry contacts open when the temperature rises above the setpoint.

Learn When Logic Solvers Are Appropriate for Overpressure Protection Systems

Learn When Logic Solvers Are Appropriate for Overpressure Protection Systems
An overpressure situation in pipes is dangerous and can lead to significant damages to property, pipe ruptures and even injuries and death. Having a system in place to prevent an overpressure situation is critical and one way to accomplish this is with a High Integrity Pressure Protection System (HIPPS).
