This unit is now obsolete. For technical support or repair please speak to our sales team or local distributor.
The SMW load cell display and controller is bulkhead mounted for strain gauge or load cell measurement applications, with analog or digital output and relay set point outputs.
The SMW weighing indicator and controller is a very flexible digital indicator and display system in a bulkhead mounting format, optimised for single or multiple load cell and weighing applications.
The digital architecture offers very easy one-pass calibration and fast setup.
This versatile Weighing Indicator and Controller Bulkhead Mounted module offers options of isolated analogue outputs, latching relays or digital outputs for control or alarm functions.
The RS232 or RS485 options provide for digital communications (including setup) and can support label or ticket printers.
Additional Features
Variable gain input sensitivity from 0.5 to 200 mV/V
Auto tare and peak hold actioned by volt-free contacts
Programmable in-flight compensation for dynamic weighing operations
Six wire input for barrier and cable compensation
AC or DC power supply options
Can be used in conjunction with our LCI load cell failure alarm, which is designed to continuously monitor the condition of individual load cells and activate an alarm when faults in the system are detected, therefore providing increased safety and cost savings onsite for all weighing systems.
