MKS R750B13TCE2GG – High-Accuracy Capacitance Manometer | Baratron® Series
Engineering Background
The MKS Baratron® capacitance manometer is the industry benchmark for absolute pressure measurement in vacuum and process environments. Developed by MKS Instruments — a global leader in gas and pressure control — the Baratron® platform has been deployed in semiconductor fabs, thin-film deposition systems, and precision chemical process lines for over five decades. The R750B series represents the ruggedized, temperature-controlled variant engineered for demanding process conditions where measurement drift and contamination resistance are critical.
Product Positioning
The R750B13TCE2GG (P/N 50412470000, cross-ref 0020-26112) is a 1000 Torr full-scale absolute pressure transducer with a heated sensor head, stainless steel wetted surfaces, and a 0–10 VDC analog output. It is designed for direct integration into process chambers, load-lock systems, and gas delivery manifolds where traceable, repeatable pressure data is non-negotiable.

System Architecture & Signal Flow
The R750B13TCE2GG operates as a passive absolute pressure reference in a closed-loop pressure control architecture:
- Process chamber → CF flange connection → R750B13TCE2GG sensor → 0–10 VDC signal → MKS 600-series controller / PLC analog input → throttle valve or pump speed command → chamber pressure setpoint maintained
- The heated sensor head is powered via the 15-pin D-sub connector; no separate heater supply required when using MKS-compatible power/readout units
- Compatible readout/controller units: MKS 670, 672, PR4000B, and third-party 0–10 V analog inputs (0 V = 0 Torr; 10 V = 1000 Torr)

Technical FAQ
Q: Is the R750B13TCE2GG a direct replacement for the standard 750B13TCE2GG?
A: Yes. The “R” prefix denotes a refurbished or remanufactured unit with equivalent electrical and mechanical specifications. Verify the serial number and calibration date label on receipt.
Q: What power supply does this unit require?
A: Standard MKS Baratron® ±15 VDC supply via the 15-pin D-sub (TCE2 pinout). Compatible with MKS 670/672 readout units and most OEM tool power rails.
Q: Can this transducer measure pressures below 1 Torr accurately?
A: The 1000 Torr full-scale range provides best accuracy in the 10–1000 Torr band. For sub-Torr or mTorr measurement, a lower full-scale Baratron® (e.g., 10 Torr or 100 mTorr range) is recommended.
Q: Is a calibration certificate included?
A: Original factory calibration documentation is provided where available. Contact us before ordering if a current NIST-traceable calibration is required — we can arrange third-party recalibration.
Q: What is the shelf life / storage requirement?
A: Store in a dry, clean environment (15–30 °C, <60% RH) with CF flange caps installed. Avoid exposure to corrosive atmospheres during storage.
