    Mattress ASTM Testing Machines

    Sigma designs two machines for SGS Govmark to evaluate mattresses to ASTM F1566-14 Specifications 

    The Durability Tester and the Cornell/Firmness tester are two standalone machines that were developed to test mattresses according to the procedures defined in the ASTM F1566-14 Specification. 

    The Durability Tester is used to test mattresses according to Section 7 of the specification and can test mattresses from twin size to queen size. The machine moves a 240 lb. roller back and forth across the mattress to simulate years of use. The roller is driven back and forth across the mattress via a servo driven belt system and once it starts it can run 100,000 cycle tests automatically without operator intervention or supervision. It features safety mat system to detect if any objects or person gets too close to the machine while operating and automatically stop all motion. The Cornell/Firmness Tester is used to test the mattresses according to Sections 6 & 9 of the specification. 

    The Cornell Tester uses a servo driven linear actuator with a two- lobe platen to continuously plunge into the mattress at 100 strokes per minute. A load cell mounted between the actuator and the platen is used to measure reactionary forces and determine how deep into the mattress to plunge. The machine then automatically stops at defined cycle counts and performs measurements on the reactionary forces of the mattress at set depths. Before and after a Durability Test or Cornell Test, a firmness test is run to determine the mattresses firmness in its “new & unused” state. The Firmness Test uses the same servo-driven linear actuator with a flat platen to plunge into the mattress at a rate of 10 inches per minute. The results during the test and changes between the before and after tests are then summarized in a table on the HMI as well as graphically for the operator and manufacturer to see the change in mattress properties over the duration of the test. 

    Services Performed: 

    Concept development, testing protocol, controls, sensors, electronics, complete fabrication including all controls, PLC/HMI, machining, validation, and testing.

  3. New Industrial Product Release Differential Pressure Alarm System

    Comments Off on New Industrial Product Release Differential Pressure Alarm System

    A New Differential Pressure Alarm System With Communications Module Model DPC-4570

    Differential Pressure Alarm Panel

    DPC-4570 SPECIFICATIONS:

    The new SIGMA DP Alarm Panel is ready to satisfy your Differential Pressure monitoring needs. The Differential Pressure (DP) Alarm Panel is a simple, easy to install and configure solution to monitor the pressure drop across a filtration media or other pressure sensitive processes. It is suitable for liquid and gas process systems.

    Using our HMI Touch Screen, the user can easily:

    Monitor inlet/outlet pressure on a continuously updating display with 0.1 PSI accuracy both locally and remote.

    • Dynamically adjust the DP alarm setpoint.
    • Monitor the current DP up to 20 PSID. A red LED stack light will turn on when the current DP pressure exceeds the setpoint value. The light can be configured to turn on solid or blink.
    • An optional audible alarm module can be added for non-visual indication. Additionally, a “dry” set of relay contacts will close (Ø1, 6A, 250 VAC). These contacts can be used to power ancillary equipment or remotely communicate with other industrial systems.

    Why Monitoring Differential Pressure is Crucial in Process Applications:

    Safety: Differential pressure measurement can also play a vital role in ensuring the safety of a process. By monitoring pressure differentials, operators can take immediate action to prevent accidents, equipment damage, and potential harm to personnel.

    Efficiency: By monitoring differential pressure with the SIGMA DP Alarm Panel, you can assess the efficiency of the fluid process and identify potential issues such as blockages, leaks, or flow restrictions. This information can help optimize the process to ensure that it operates at its maximum efficiency.

    Quality Control: In industries where precise control of fluid flow is essential for maintaining product quality, monitoring differential pressure becomes critical. Deviations in pressure can indicate changes in the composition, viscosity, or density of the fluid being processed, which can affect the quality of the end product. Regular monitoring with the SIGMA DP Alarm Panel allows for quick detection and correction of any issues that might compromise product quality.

    Process Control: Many industrial processes require precise control of fluid flow rates to achieve desired outcomes. Using the SIGMA DP Alarm Panel, operators can adjust control valves and other equipment to maintain the desired pressure differentials, thus ensuring that the process operates within the specified parameters.

    Equipment Health Monitoring: Changes in differential pressure can often signal equipment wear and tear or clogging. By regularly monitoring pressure differentials across filters, heat exchangers, and other components, maintenance teams can schedule preventive maintenance activities, reducing the likelihood of unexpected breakdowns and downtime.

    Energy Efficiency: In systems where pumps and compressors are used to maintain fluid flow, monitoring differential pressure with the SIGMA DP Alarm Panel can help optimize energy consumption.

    Regulatory Compliance: Is your industry subject to strict standards related to process conditions? Differential pressure measurement can provide documentation of compliance by demonstrating that pressure differentials are being maintained within specified ranges.

    Troubleshooting: When an issue arises in a process, differential pressure measurement can provide valuable diagnostic information. The SIGMA DP Alarm Panel can detect sudden changes in pressure, which can help operators identify the location and nature of the problem, enabling faster troubleshooting and resolution.
