The Ashcroft A4 intrinsically safe and non-incendive 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 intrinsically safe and non-incendive pressure transmitter 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.

The Ashcroft A4 has a response time of less than 2ms, with pressure ranges available in vacuum, gauge, compound, and absolute pressure from 0 to 5 psi through 0 to 10,000 psi. Equivalent ranges in bar are also available. The Ashcroft A4 pressure transmitter is available in three accuracies: 0.25%, 0.5% or 1.0% and has a 4-20mA output signal. Wetted materials are made of 316L stainless steel and the case is made from 304 stainless steel.

The Ashcroft A4 intrinsically safe and non-incendive pressure transmitter is ideal for oil field equipment, upstream oil and gas production, natural gas compression, alternative energy projects, and transfer control applications.
