Ashcroft AM2-1 Quick-SelectTM Pressure Calibrator Module (Medium-High Range)

Quick-Select™ Pressure Modules
Available in full-scale ranges from 0.25 inches H20 through 10,000 psi. Gauge, vacuum, absolute, differential or compound pressure ranges are available.
Select from multiple modules that can be quickly interchanged (“hot-swapped”) without the use of tools, and are automatically recognized once installed in the base unit.

Ashcroft Low Pressure Module AM2-1
The AM2-1 Quick-Select low pressure module is based on a proprietary, variable-capacitance sensor.  This sensor is available in ranges from 0.25 to 0/200 inches H20 with accuracies from ±0.1% to ±0.06% of span, and are available for gauge, differential and compound pressures.
They are suitable for use with dry, non-corrosive gases. The variable-capacitance sensing element incorporates a micro-machined silicon diaphragm. Silicon provides optimum repeatability with minimal hysteresis. The sensor is extremely stable, due to the sputtered metal capacitance plates being molecularly bonded to the silicon. This design eliminates adhesives from the sensor assembly.
The AM2-1 sensor is also extremely rugged. It can withstand extreme overpressure, shock and vibration without significant error or calibration offset.

Ashcroft Medium / High Pressure AM2-2
Module AM2-2 The AM2-2 Quick-Select pressure module incorporates a piezoresistive, micromachined silicon sensor. These sensors are available in ranges from 5 psi through 0-10,000 psi, and are also offered in absolute, vacuum and compound ranges with accuracies from 0.025% to 0.1% of span. 316 SS sensor isolation is provided on all ranges except for 10,000 psi which is 17-4 PH stainless steel, and is suitable for applications involving fluids or corrosive gases.

Optional enhanced accuracy eliminates temperature error over the entire compensated temperature range of high pressure modules.
