Signal Conditioning

Micron Meters line of Analog Output Strain Gauge Signal Conditioning Modules offers a flexible solution for any Analog requirement.

High Speed (up to 6 kHz)

From miniature PCBs to panel instruments or bulkhead / DIN rail mounted units, We can provide high speed (up to 6 kHz) and high stability analogue outputs in 0-10 V, 0-5 V, ±10 V, ±5 V, or 4-20 mA.

4-20 mA ATEX Intrinsically Safe

Designed to work in Zones 0, 1, 2 the device can be connected to ATEX approved equipment including strain gauges, load cells, pressure and torque transducers within the hazardous zone or to non-approved ATEX equipment outside the hazardous zone, with a suitable barrier.

PCB only versions of the signal conditioning modules are also available, giving OEMs the opportunity to integrate modules into their own systems, creating new products to their specifications.

What is a Signal Conditioner?

A signal conditioner is a device that converts an electrical signal into another form of signal that is more useful to the user. Load cell signal conditioning may include amplification, attenuation, excitation, filtering and isolation.

Amplification

Generally, an amplifier is a device that converts a small signal into a proportionally larger signal.

Attenuation

Attenuation is the opposite of amplification.

Excitation

The external application of electrical voltage applied to a transducer for normal operation.

Filtering

Filters reject unwanted noise within a certain frequency range.

Isolation

Is used to break ground loops, blocks high-voltage surges and reject high common-mode voltage. This protects both the operators and the measuring equipment.

Load Cell Controllers

The  weighing controllers and alarm modules offer precision control of weighing, temperature and other process variables together with a host of advanced features not normally found in this class of weighing controller. These weighing controllers offer simple calibration and configuration with options for additional outputs such as 4-20 mA/ 0-10 V analogue outputs and communications ports for connection to PC’s, PLC’s printers and remote displays.

With our products the emphasis is on simplicity and ease of use. A simple 'QuickStart' section in the manual can be used to configure all the functions essential for controlling your process. This includes input sensor type, measurement range, control options and alarms - making 'Out of the Box' operation truly achievable. If you prefer, you can specify what you need at point of order and we will ship the unit preconfigured to your requirements.

LCA20 Load Cell Weighing Controller

One of the most popular products is the LCA20. This load cell amplifier and weighing indicator (LCA20) offers options of local or remote LCD displays, isolated 4-20 mA 0-10 V analogue outputs, relay outputs for control or alarm functions and in-flight compensation commonly used in crane overload alarms. The RS232 or RS485 options provide for digital communications (including setup) and can support label or ticket printers.

Controls and Alarms

It is both a safety and a regulatory requirement to control. For monitoring of multi-load cell installations such as silos, tanks and other systems where the failure of a load cell could be catastrophic then take a look at the LCI.

LCI Load Cell Controller Modules

The LCI load cell controller modules constantly samples the individual load cell channels and activates an alarm if any failure conditions are detected. For a simple summing circuit with no trimming and no corner compensation, use the Load Cell Junction PCB, model JPP Load Cell Junction PCB, and for trimming and corner compensation, use the Active Junction Box, model JBA Load Cell Junction Box.
