MKS 1350-01083 Replacement for Baratron Series

Product Overview

MKS 1350-01083 Replacement for Baratron Series: Smooth Transition & Legacy System Compatibility

The MKS Instruments 1350-01083 is a Baratron® capacitance manometer designed for precision vacuum pressure measurement in semiconductor fabrication, thin-film deposition, chemical vapor deposition (CVD), and industrial process control environments. As legacy vacuum process systems age and OEM support for discontinued Baratron variants becomes increasingly limited, facilities engineers and procurement teams face mounting pressure to source reliable, specification-matched replacements that minimize process disruption and avoid costly recertification cycles.

This unit is a direct replacement and upgrade solution for the MKS Baratron 1350 series, offering full backward compatibility with existing signal conditioning infrastructure, vacuum chamber feedthroughs, and process controller interfaces. Whether you are maintaining a legacy Applied Materials, Lam Research, or Tokyo Electron (TEL) process tool, or upgrading a standalone vacuum furnace or load-lock chamber, the 1350-01083 integrates without requiring modifications to your existing wiring harness, mounting flange, or controller input card.

Seamless Upgrade Solutions

Replacing the 1350-01083 in a live vacuum process system is rarely an isolated task. In most retrofit scenarios, the manometer replacement is part of a broader instrumentation refresh that may also involve the MKS 670B signal conditioner or the MKS PDR-C-2C power/display unit, both of which interface directly with the Baratron transducer and must be verified for output range compatibility before commissioning the replacement unit. If your facility is also upgrading the mass flow control loop, the MKS 1179A or MKS 1259C mass flow controller shares the same analog signal architecture and can be recalibrated in parallel with the manometer swap, reducing total downtime to a single maintenance window.

For systems where the vacuum chamber pressure is monitored alongside a Pirani or cold cathode gauge — such as an MKS 910 DualTrans or an MKS 972B DualMag — the 1350-01083 replacement can be integrated into the same multi-gauge controller without reprogramming the pressure setpoints, provided the controller firmware supports the Baratron analog input range. In older process tools using an MKS 651C or 653B pressure controller for throttle valve management, the manometer output feeds directly into the pressure control loop; replacing the sensor without verifying the zero and span calibration of the 651C can introduce process drift, so a calibration verification step is recommended post-installation.

Facilities managing multiple vacuum chambers on a shared gas panel may also need to inspect the upstream MKS 1479A or MKS 1580 gas delivery manifold components for compatibility with the updated sensor signal. In cleanroom environments where the process tool communicates via RS-232 or DeviceNet to a SCADA or DCS host, the analog output from the 1350-01083 is typically converted through an I/O module on the tool’s local controller — no protocol changes are required at the field device level, making this one of the lowest-risk sensor replacements in a vacuum process retrofit program.

Retrofit Guidance FAQ

Q: Does the 1350-01083 require rewiring when replacing a legacy Baratron unit?
A: No. The 1350-01083 uses the same 15-pin D-sub connector pinout as the standard Baratron series. Existing cables and harnesses are reused without modification.

Q: Is the output signal compatible with my existing MKS 670 or PDR-C-2C controller?
A: Yes. The analog output (0–10 VDC) is fully compatible with MKS 670, 670B, and PDR-C-2C signal conditioners. No controller firmware update is required.

Q: Can this unit be installed in the same flange position as the original?
A: Yes. The 1350-01083 maintains the standard Baratron physical envelope and flange interface (CF/VCR/KF as applicable), allowing direct drop-in installation without chamber modification.

Q: What communication protocol does this sensor use?
A: The 1350-01083 outputs a standard analog voltage signal. It does not require EtherNet/IP, PROFIBUS, or any digital fieldbus configuration — it integrates directly into existing analog pressure control loops.

Q: How do I verify calibration after installation?
A: After installation, perform a zero-point calibration at base pressure using the connected signal conditioner. Span verification should be conducted against a reference standard or transfer standard at the process operating pressure.

Q: What if my process tool uses a different pressure range than the original sensor?
A: Confirm the full-scale range of the 1350-01083 against your process operating pressure. MKS Baratron sensors are range-specific; if the process range has changed, a different Baratron variant may be required. Contact us for range-matched alternatives.

Q: Is this unit suitable for corrosive gas service?
A: The standard 1350-01083 is configured for general vacuum process gases. For corrosive or reactive gas applications (e.g., HCl, HF, Cl₂), confirm the wetted materials specification before installation.
