Description
Emerson LCP100 — Process Weighing Indicator
The Emerson LCP100 is a process weighing instrument designed for industrial weighing applications. It is part of Emerson’s portfolio of weighing and measurement solutions, widely used across manufacturing, food & beverage, chemical, pharmaceutical, and logistics industries.
What It Does
At its core, the LCP100 is a weight indicator and controller — it receives low-level millivolt signals from load cells, converts them into accurate weight readings, and provides real-time display, data logging, alarm management, and communication with higher-level control systems. Think of it as the “brain” sitting between your load cell and your PLC/SCADA.

Key Features
High-precision weighing — The LCP100 delivers accurate weight measurement suitable for demanding process environments. It accepts signals from strain-gauge load cells (typically 1–4 cells) with mV/V excitation and provides high-resolution A/D conversion.
Multiple measurement units — Supports kilograms, pounds, grams, and other units, configurable per application. This makes it versatile across regions and industries.
Data display and recording — The unit features a real-time display showing live weight, tare, net weight, and accumulated total. It supports data logging and storage, enabling operators and engineers to review weight trends over time — critical for quality control and batch documentation.
Alarm functionality — Upper and lower limit alarms can be set. When weight exceeds or falls below the preset thresholds, the LCP100 triggers visual and/or relay alarms — alerting operators immediately to overfill, underfill, or process deviations.
Wide temperature range — Operating from -40°C to +100°C, the LCP100 handles extreme environments — from frozen food processing to hot chemical plants — without drift or failure.
Communication interfaces — Equipped with standard industrial communication ports (typically RS-232, RS-485, and optionally Modbus), the LCP100 integrates seamlessly with PLCs, DCS, SCADA systems, and Emerson’s own DeltaV platform. This enables remote monitoring, recipe-based batching, and centralized data collection.
Robust and reliable — Built with industrial-grade components, the unit is designed for continuous 24/7 operation with minimal maintenance. Its compact form factor fits standard panel or DIN-rail mounting.
Typical Applications
The LCP100 thrives wherever precise, continuous weighing is required:
- Batching and dosing — Pharmaceutical, chemical, food ingredients measured into mixers or reactors
- Belt / conveyor weighing — In-motion weighing of bulk materials on conveyor belts
- Tank and hopper weighing — Monitoring inventory in silos, tanks, and process vessels
- Packaging — Check weighing, fill-level control, and quality assurance on packaging lines
- Raw material and finished goods weighing — Production process control and inventory tracking
- Reactor vessel monitoring — Tracking material weight during chemical reactions or batch processes
How It Fits in the System
A typical setup looks like this:
Load cell(s) mounted on a tank, hopper, or conveyor → shielded cable → LCP100 indicator (provides excitation voltage, reads mV signal, computes weight) → RS-485 / Modbus → PLC or SCADA → operator HMI showing real-time weight, totals, and alarms
The LCP100 can also operate standalone with local display and keypad for simpler applications where PLC integration is not needed.
Compatible Load Cells
The LCP100 works with standard strain-gauge load cells — including Emerson/BLH Nobel KIS-series, and competing brands from Vishay, HBM, Mettler Toledo, etc. — as long as the cell output is in the mV/V range (typically 2 mV/V). It supports 4-wire load cell connections with automatic sense lead compensation.
Status & Availability
The LCP100 is an active Emerson product — not obsolete. It remains widely used in existing plants and is still available through Emerson authorized distributors. Lead time is typically 4–8 weeks for new units; stock items may ship within days. Pricing varies by region but generally falls in the mid-range for process weighing indicators.
Bottom Line
The Emerson LCP100 is a rugged, high-accuracy process weighing indicator built for continuous industrial use. With support for multiple load cells, wide temperature operation (-40°C to +100°C), built-in data logging, alarm management, and standard industrial communication, it is a proven workhorse for batching, conveyor weighing, tank monitoring, and packaging applications. If your plant runs Emerson DeltaV or needs a reliable standalone weight controller, the LCP100 is a solid, well-supported choice.
