ONEhalf20 Products FAQ
The most Frequently Asked Questions on our ONEhalf20 products are :-

Where did the name ONEhalf20 originate?

ONEhalf20

The name ONEhalf20 originated from the ½-20 UNF mounting hole found on today’s modern plastics processing machine.


What types of devices mount into this ½-20 UNF hole?

Melt Pressure Transducers, Rupture Disks or Burst Plugs, as well as Melt Temperature Sensors or Blank Melt Bolts.

Melt Temperature Sensor

Are your products compatible with other makes/models?

ONEhalf20 Products

Yes. All of our melt pressure transducers offer 100% form, fit, and function with those products manufactured by Dynisco, Gefran (ISI), Gentran, GP50 and others. ONEhalf20 transducers are 100% field compatible with all melt pressure transducers utilizing the Bendix 6 pin connector. There is never a need to rewire when installing a ONEhalf20 melt pressure transducer. In addition all ONEhalf20 transducers come complete with a 25’ interconnecting cable assembly at no additional charge. All other manufacturers charge extra for this often required item.
See below for the compatability lookup table for some other major manufucturers' models.

How are the products manufactured?

All ONEhalf20 products are manufactured under an exclusive licensing agreement. The products are manufactured in an ISO9002 certified manufacturing plant utilizing a proprietary process, with Canadian design, engineering, and quality assurance.


What warranties do the products carry?

All ONEhalf20 products (excluding rupture disks, melt temperature sensors, and accessory items) carry a full 2 year warranty covering manufacturing defects. All products undergo a rigorous 100% total quality inspection, in addition to full testing prior to shipment. All products ship with a detailed performance data certificate indicating actual accuracy, repeatability, hysterisis, and drift. NIST traceable calibration certificates are available.


Are your melt pressure transducers repairable?

Melt Pressure Transducer

Yes. All ONEhalf20 melt pressure transducers are repairable. Repairs and or re-calibration are carried out at our head office, just contact us via the details on our "Contact Us" page (see menu, left).


Why are your products significantly less expensive than the competition?

ONEhalf20 engineers spent considerable time reviewing common manufacturing technologies presently employed by other manufacturers. This research revealed many weaknesses in the non-automated assembly techniques used by our competitors. ONEhalf20 engineers were able to fully automate these processes with the result being significantly improved and consistent product quality along with vast improvements in manufacturing costs and times. Griffith & Thomas can then pass on these savings to you.
