New Product Alert: Lower Cost 6 mm Cavity Pressure Sensor Coming April 3
RJG’s new 6 mm cavity pressure sensor will be released to the public on April 3, 2017. The 6 mm sensor is ideal for high cavitation molds with small, tightly packed ejector pins. It allows customers to measure cavity pressure in order to improve quality and reduce costs.
There will be two models available, one rated to 50 pounds for use with the ejector pins up to 2 mm diameter, and another rated to 250 pounds for pins up to 4.5 mm diameter. The 50 pound model will be available on April 3, and the 250 pound model will be available in the coming months.
The 6 mm sensor is a robust, indirect (under the pin) pressure sensor that works in conjunction with the eDART System™ to assist molders in diagnosing processes and automatically sorting suspect parts. The 6 mm sensor head is the smallest strain gage sensor available, permitting the use in molds that may have tight clusters of pins with limited room.
The new model is designed with a sensor head that matches the dimension and installation pocket of the Piezoelectric 9211 6 mm button. That means it contains all of the capability of the Piezo at a more cost effective price—approximately 20% below comparable Piezo Multi-Channel Systems. Unlike Piezo, though, the connector cables can be bent and folded without damage, making them more flexible and easier to maneuver around obstacles.
Features of the 6 mm sensor include:
- 6 mm diameter and height
- Flexible, robust, order-to-length cables
- Not susceptible to moisture or contamination
“Smaller sensors are becoming more popular as part complexity and cavitation increases,” said Mike Groleau, Project Manager at RJG. “Our new sensor provides an alternative to the current Piezo technology that reduces cost while improving data reliability.”
The 6 mm sensor is part of RJG’s Multi-Channel Strain Gage sensor line, which was designed to simplify in-mold installations for molds with four or more sensors and save real estate in the mold. This multi-channel cavity pressure solution, unique to RJG, allows injection molders to connect up to eight strain gage sensors to one connection point on the mold.
