Description: Auction is for (1) Used in Excellent Condition, an MKS Baratron Type 122A as shown in the pictures. Auction is for Baratron 122A only. The MKS Baratron® Type 122A Absolute Pressure Transducer marks the beginning of a new era in low cost pressure measurement. Using a latest-generation single-sided dual-electrode Inconel® sensor coupled with a new fixed-frequency bridge signal conditioner, the 122 provides operation which is inherently temperature stable at zero pressure, capable of withstanding high overpressure conditions with minimal or no shifts in output over its range, and high resistance to corrosive environments. The variable-capacitance sensor is the result of over 25 years of research, development and customer experience in total pressure measurement. The design incorporates a tensioned metal diaphragm (Inconel), one side of which is exposed to the gas whose pressure is to be measured. The other (reference) side of the diaphragm contains a dual electrode assembly (previously found in premium transducers only) sealed in a high vacuum reference cavity which is maintained by a chemical getter system. The signal conditioning electronics board contains a fixed-frequency oscillator, balance-sensing circuit, linearization circuitry and amplifiers which provide a 0 to 10 Volt DC full scale output. The signal conditioner is inherently temperature stable at balance (pressure = 0 Torr) and is selfcompensating with temperature changes at other pressures. A drawn aluminum can forms the protective cover for the transducer and a PC board mounted removable terminal block allows connections to be easily made for ± 15 VDC power inputs and the 0 to 10 VDC pressure signal output. In addition, the aluminum cover works in conjunction with an inner PC shield board with RF bypass capacitors to virtually eliminate RFI and EMI. Refer to Figure 5, page 12, for a cross sectional view of the 122 transducer. Please make sure of compatibility PRIOR to purchase.We look forward to shipping this out immediately with tracking and insurance. Thank you for considering our vacuum related items.
