Omegadyne announces the most durable version of its high accuracy MM Series micro-machined silicon pressure transducers. The new hermetically sealed version of the MM Series features all welded Stainless Steel construction, 316 wetted parts and glass to metal seals (GMS) at the electrical outlets. This ensures that the unit is hermetically sealed from external environments and the media. Designed for use on automotive and aircraft test platforms and anywhere environmental concerns demand the most durable characteristics.
The sealed MMA500V Series has a micro machined silicon core that provides high accuracy, low drift and excellent long term stability in the harshest environments. Ranges from 100 psi to 5000 psi, accuracies from 0.08% to 0.03% and a variety of pressure and electrical connections make this MMA500V Series Transducer extremely versatile. The temperature compensation range can be as broad as -40 to 200*F (-40 to 104*C) and thermal errors as low as +/- 0.3% over the compensated range. Operating temperature range is -49 to 250*C (-45 to 121*C). The MMA500V Series design is further ruggedized with a secondary containment system in the event of diaphragm rupture. A 5-Point NIST traceable calibration certificate included.
The MM Series pressure transducers offer “Custom Designed” features with fast delivery. Our modular design allows you to construct a pressure sensor to meet your application requirements, with guaranteed fast delivery… typically from stock to 2 weeks. Our product configurator found online at omegadyne.com allows quick and easy configuration of a transducer that meets the exact needs of your project.
Web-Enabled Ultrasonic Sensors

LOGAN, UT – Automation Products Group, Inc. (APG) introduces LOE Web-Enabled Ultrasonic Level Sensors. These self-contained ultrasonic sensors provide a low-cost, tailored sensing solution for monitoring liquids or solids in remote tanks, and can also be used for local tank monitoring applications.
LOE ultrasonic sensors feature Power Over Ethernet (POE) for easy wiring, AutoSense software for hassle-free operation, and can be easily programmed and configured remotely – without requiring any configuration software – via APG’s levelandflow.com website, and locally via the sensor’s embedded web page. Sensor level data is transmitted to a dedicated website that utilizes an open-source MySQL database format to ensure user data is available in any format that might be required of the application.
Three models are available. The LOE-2126 provides a detection range of 1 to 25 ft., the LOE-3136 provides a detection range of 1.5 to 40 ft., and the LOE-6126 provides a detection range of 4 in. to 180 in. The LOE-6126 delivers a best-in-class blanking distance of just 1 in., compared to 4 in. for most other competitive sensors, which uniquely enables a single sensor to monitor the entire tank or vessel range.
Sensor readings are uploaded to a database via a standard Ethernet (TCP/IP) connection, where the level or volume information can be viewed from any computer with internet access, via a password-protected web page. The sensor and/or the web-server can be user-programmed to trigger the website to send an email, text message or both when a predetermined level or volume is reached. These sensors also feature two internal relays that can be programmed to control pumps or activate local alarms.
Sensor parameters and settings can be changed at any time via the sensor’s internal web page, which is readily accessible by simply entering the sensor’s IP address into any internet browser on any computer connected to the same network. The internal web page also displays the level or volume information, effectively turning any computer on the network into a potential remote tank display/monitor.

Plainville CT — Gems® Sensors & Controls™ (Gems) has launched the UCL-510 Ultrasonic Level Sensor. The compact UCL-510 is suitable for non-contact applications such as industrial water treatment, wastewater management, chemical storage, and many other challenging fluid applications.
The UCL-510 offers an innovative solution for challenging fluid measurement with no moving parts. This highly accurate and reliable sensor is built for general purpose, small tank applications 49.2” (1.25m) or less and offers switch, controller and transmitter capabilities in one multi-function transmitter. The UCL-510 is packaged within a compact sensor with a 2” dead band and an innovative PC interface that provides fast and accurate configuration. The UCL-510 is suited for corrosive and dirty applications and is virtually maintenance free and reduces tank system hardware. The product combines 4 relays, 4-20mA output and pump/valve control in one small sensor for a total fluid handling and automation solution.
