FAST Response!

Transmitters with 1 millisecond response time.

Last year we spotlighted a new design we'd done for a customer needing a quantity of fast-response transmitters. We've now turned it into a standard product offering.

Available on most of our DIN-rail transmitters (JH5000 Series), Option HS output is approximately complete (95% response) in 0.001 seconds. It is not available on AC input or frequency input transmitters, as these require filtering to function properly.

Frequency response is 3dB down (0.707 times the DC gain) at approximately 600 Hz.

Faster (or slower) available - contact us!

Fast Response - Part 2

Speedy - Part 2

(See August 16 for Part 1)

Part 1 announced fast-response instruments. This time we're promoting our fast response to customer needs.

Thursday afternoon: We received two urgent calls, two different customers, asking "can you do it" and "how fast"? One was for 10 pieces of a standard product; the other, 6 specials which required modest new circuit design. We were able to say "Yes" to both.

Friday morning: Received both orders.

Friday evening: Two of us (Rick & Harry) stayed late.

Saturday: Rick & Harry worked from about 8:00 until 2:45PM. Finished both orders.

Monday: Both orders shipped. (Of course, both customers paid expediting charges to cover our overtime.)

Details: The standard-product order (JH4001I RTD Transmitters) was from a Navy base. They had been using "Brand A" products but that company was not able to delivery quickly. They sent searching and found us on the web. We did not have any in stock either - so we worked the weekend!

The special requirement was for an absolute-value transmitter. (See our posting of October 3, 2009 for more detail.) We had done this before (as a special in 2001) but the detailed requirements were different on this time. Thursday evening calculations plus weekend assembly and test got the job done.

Conclusion: If you need action, call us.

Fast Response

Speedy!

OK - maybe you're expecting me to promote our fast response to your orders. (Sneaky how I worked that in!)
The real topic - fast-responding signal conditioners.
A few months ago a customer asked if we could provide frequency response to at least a few kilohertz for DC and load cell signals. Our standard circuitry could not. His quantity requirements were large enough that we designed a new circuit to meet his needs (3kHz minimum). We've since shipped his order. He tells it is working well in his application - heavy-duty shock testing. More recently another customer needed just three fast-response units which we now are able to easily supply.
We're working on the paperwork and documentation to turn this in to a standard catalog product line of DIN-rail mount transmitters. Look for it shortly.
Meanwhile, if you have high-frequency or fast-response requirements, please ask us. E-mail jhtek@jhtechnology.com or call (800) 808-0300 (US toll-free) or (941) 927-0300.
