Model A4 Intrinsically Safe & Non-Incendive Pressure Transmitter
Brand: Ashcroft IncThe Ashcroft A4 Pressure Transmitter is ideal for a broad spectrum of pressure sensing requirements where Intrinsically Safe or Non-Incendive hazardous location ratings are required.
The Ashcroft A4 is designed and manufactured to provide the user with accurate, reliable, and stable output data.
This is accomplished through the use of an on board microprocessor, that is programmed during a unique digital compensation process, to provide extremely linear and precise performance over the entire specified pressure and temperature range.
