SILOWEIGH II Pro – silo, vessel or bin weight with touch screen interface

Designed for use on up to 6 vessels per location where only local readings are required.

The accurate silo level and inventory system for bins, tanks and storage vessels that you can install yourself. SiloWeigh II Pro tells you the contents of any silo, feed bin, tank or storage vessel.

SiloWeigh measures the actual weight of the vessel and contents to give a true picture of the amount on hand. 

SiloWeigh II Pro pairs the L-Strain or Silex sensors with a touch-screen display, to measure silo level by weight.  Capacity is up to 6 vessels displayed as bar-graphs or a trend-graph of each individual vessel. 

A special display shows weights of past deliveries to detect shortages.

Never run out of material again
  • Never run out of material again – Visual warning at Reorder and Low levels, plus audible warning if you need it, to prevent loss of production and missed deliveries.

  • Eliminate the risk of overfilling – Blown filters and the ensuing environmental hazards are a thing of the past.

  • Identify and stop delivery shortages – Ability to check deliveries, against the delivery ticket. 

  • SiloWeigh is the perfect solution for accurate inventory monitoring of legged or skirted silos, bins or tanks. It is better than  level measurement, as SiloWeigh measures the actual weight of the vessel and its contents.

The silo or bin weight is shown by a bar-graph and you can touch this to see a trend graph that measures deliveries
SiloWeigh II Pro's cabinet and touch screen are dust and splashproof for use in rough environments
Specifications

Silo Capacity and stress:

All silo capacities can be measured. The limitation is the stress in the support structure. Acceptable stress is in the range 1500 to 15,000 lb per square inch.

Vessel support structure, material type:

All types of steel, stainless steel and aluminum. 

Number of sensors:

Up to 48 sensors can be powered from each SiloWeigh II display cabinet. 

Display type, basic model:

3.5" and 5.7" (89 and 145 mm) touch screen shows 6 bar graphs for up to 6 vessels, plus digital display of % full and weight or volume. 

Remote WiFi Viewer: 

External Android devices communicate with the display unit by WiFi radio, through a wireless router, giving the same resolution and features as the main display unit. 

Display accuracy and resolution:

Digital transmission from vessels; overall accuracy of digital section 0.1%. 

Overall system accuracy:

Dependent on structure being measured. Typically ±2% of full scale value for legged silos and ±5% for skirted silos 

Analog outputs: 

2 isolated outputs, continuous or multiplexed to include all vessels. 0-20mA, 4-20mA, 0-10V, 12 bit. 

Analog inputs: 

2 inputs 0-20mA / 4-20mA 13 bit, 2 inputs thermocouple temperature. 

Digital alarm outputs: 

6 transistor 'sourcing' outputs, 24 VDC, 300 mA, fully programmable as audible (pulsed) or continuous alarms activated by any combination of 4 levels for each vessel. 

Optional digital outputs: 

10 transistor outputs as above, 22 inputs as below, in place of analog I/O. 

Relay option: 

Converts outputs to isolated dry contacts, 5A at 250 VAC and inputs to isolated relay coils, 110 VAC standard, 24 V AC/DC or 220/250 VAC optional. 

Digital inputs: 

8 inputs 24 VDC, act as Audible and Master alarm cancel or programmable inputs to display warning messages: example - used with silo overpressure switches warns that filters are blocked. 

Power:

110-250V AC, 50 W max. Solar power also available. 

Temperature Range:

Sensors: -40 to +70°C (-40 to +160°F). Display: 0-50°C (32-120°F). 

Display Construction:

ABS plastic, chemical resistant, NEMA-4X. 

Display Cabinet Size

Regular cabinet holds touch screen, power supply and optional I/O relays, 13"x 13"x 8"deep (330 x 330 x 203 mm). 

Safety Certifications:

CE, UL and CUL
