Transmitters

Devices that take the raw signal from a sensor and convert it into a standardized, long-range signal (such as 4-20mA). This ensures accurate data transmission to controllers over long distances without interference.

Emerson | Rosemount™ Transmitters

The Rosemount brand is the “gold standard” for pressure and temperature transmitters. They are sourced for their extreme reliability and “Power Advisory” diagnostics, which can actually detect if the wiring loop is corroding or if water has entered the housing before the device fails.

Rosemount 3051

Model Number: 3051CD2A22A1AB4M5

The industry standard; Coplanar™ platform for integrated manifolds; 10-year stability.

Key Technical Specifications:

  • Built-in external buttons allow for commissioning and zero-trimming in the field without a handheld communicator.

  • Continuously monitors the electrical loop to detect issues like corroded terminals or power supply fluctuations.

  • Secure wireless configuration and maintenance from up to 50 feet away using the AMS Device Configurator app.

Rosemount 644

Model Number: 644HAI1

Head, field, or rail mount; supports RTD and Thermocouple; dual-compartment housing.

Key Technical Specifications:

  • Can automatically switch to a secondary sensor if the primary fails, preventing process shutdowns.

  • Eliminates interchangeability errors by matching the transmitter to the specific curve of the RTD sensor (Callendar-Van Dusen).

  • Designed and certified to IEC 61508 for use in safety-instrumented systems (SIS).

Endress+Hauser | Cerabar & iTEMP

Endress+Hauser is a leader in “Smart Blue” technology. They are frequently sourced for their intuitive wizards and the Ceraphire™ ceramic sensor, which is nearly as hard as a diamond and perfect for measuring abrasive slurries or corrosive acids that would destroy stainless steel.

Cerabar PMC/PMP

Model Number: PMP51-AA21JA1HGBGCJA

Ceramic (PMC) or Metal (PMP) diaphragms; Heartbeat Technology™ for self-verification.

Key Technical Specifications:

  • Dry, oil-free measuring cell that is vacuum-proof and highly resistant to abrasion and chemical attack.

  • Provides 24/7 internal diagnostics and documented proof-testing without interrupting the process.

  • A removable data module that stores all device parameters, making hardware replacement “plug-and-play.”

iTEMP TMT

Model Number: TMT82-NAA2DA1A1AAA1

High-accuracy digital transmitters; available with IO-Link or 4-20mA HART communication.

Key Technical Specifications:

  • Can measure two separate temperature points simultaneously or use them for differential temperature calculation.

  • Detects sensor drift and corrosion, alerting the PLC before the measurement becomes inaccurate.

  • Full configuration and diagnostics via secure Bluetooth, even in hard-to-reach or hazardous areas.
