Intrinsically Safe Preamplifiers & Barriers

The Intrinsically safe preamplifiers are used in hazardous, gaseous environments that require class IIC, Intrinsically Safe (IS) apparatus. The IS preamplifiers are designed and certified for use within the hazardous area, while the barrier is attached to the preamplifier and is installed outside the hazardous area where it is connected to the AE instrument. Therefore, this series of sensor and preamplifier is used when the AE system can be installed outside the hazardous area. The IS preamplifiers must be used in combination with the listed IS sensors and barrier. They feature selectable gain, pluggable High Pass and Low Pass filters, and operate with MISTRAS’ standard single Power/Signal BNC.
