Description
The Yokogawa \muR1800 (UR1800) is a high-performance industrial strip chart recorder featuring an 180 mm effective recording width. It acquires, displays, and permanently logs multi-channel process parameters—such as temperature, pressure, flow, and voltage—across continuous paper charts while providing real-time digital indication and alarm monitoring for critical industrial environments.

Engineering and Integration Notes
In field deployments across power generation, chemical processing, and heat-treating facilities, the \muR1800 serves as a reliable, hard-copy data logging safeguard independent of computer network architectures.
- Universal Input Setup: Configuration is handled via front-panel keys rather than internal hardware jumpers. Ensure input types (TC, RTD, or mV/V) are matched correctly in the software setup menu prior to applying live field signals to avoid input stage damage.
- Panel Depth Considerations: The recorder features a compact housing depth (approximately 220 mm behind the panel face), making it suitable for tight control room console retrofits. Maintain adequate rear clearance for terminal wiring and power connections.
- Signal Shielding: Terminate thermocouple extension wires and analog signal shields cleanly to the rear terminal board grounds to minimize common-mode electrical noise and prevent erratic trace calibration.
Frequently Asked Questions
What is the primary operational difference between the pen and dot models?
Pen models use individual physical pens (up to 4 channels) to provide continuous analog traces with high response speeds. Dot-printing models use a high-speed wire dot matrix mechanism to sequentially print multi-channel data (up to 24 channels) using a multi-color ribbon cassette on a shared 180 mm chart grid.
Can the unit store data digitally in addition to paper recording?
Depending on the specific suffix and hardware option codes installed, many units support external memory media (such as IC memory cards or data storage options) to back up trend data and configuration files digitally alongside the physical paper log. Verify exact options on the unit’s nameplate before deployment
