350 IS Series with LED Display
Hazardous Area Weighing
The Model 350 I.S. and Model 355 I.S. are designed to be intrinsically safe in hazardous environments and meet global standards in metrology and electrical safety with precision weighing. Smart features such as quick calibration, fast update rate, and process control configuration offer value-added flexibility. They are designed for use in multi-level applications and provide operator access for monitoring and controlling actions based on weight values.
The Model 350 I.S. Indicator is ideal for applications where only the weighing event occurs. Where a keypad is required, the Model 355 I.S. Indicator is the perfect choice.
We offer a choice of display types to suit your application. When an indicator is located outside or in direct sunlight, the LCD (Liquid Crystal Display) Backlit Display maintains excellent readability. Installation locations with low or no light will benefit with indicator models that have the bright, crisp LED (Light Emitting Diode) Display.
These indicators can be powered by a battery pack in the hazardous area for applications where access to main power is an issue. The battery module is mounted on the indicator swivel bracket and the indicator has an annunciator to warn when the battery requires a recharge. Battery recharging must occur in a safe area. There is also a sleep mode feature for extended battery life. For applications where the indicators are providing data or controlling actions, a continuous power source is an available solution.
Ideal Indicator for hazardous areas
These indicators offer advanced precision weighing and process control within a hazardous area. Applications where they are used include fertilizer processing and loading, ink manufacturing and blending, gaseous or liquid fuelling stations, chemical development and mixing and paint processing and filling.
Choice of LED / LCD user display
The 350 and 355IS come with a choice of LED or LCD user displays, to suit a particular application. The indicators can also have a choice of power, either AC/DC or a rechargeable battery pack.
