Lick and Stick Sensors...take a look!

Dave Kaufman from Honeywell and I have been talking about the coming of new and really inexpensive sensors that will enable the use of multiple sensor arrays in many process applications. Dave called them "lick and stick" sensors. They won't be as accurate as the very high accuracy single point sensors we use now, but they won't need to be either. Here's an example of exactly what we've been talking about, from a company called Spectrum Sensors and Controls: New Fast Response, Water Temperature Sensor for Pools and Spas St. Marys, PA—July 25, 2008—Spectrum Sensors and Controls introduces "AquaSense" Water Temperature Sensor, a new product designed for pool and spa applications requiring ease of installation and a fast temperature response time. The new sensor, which is housed in a rugged, molded shell, is compatible with most major pool/spa control systems on the market today. The standard AquaSense sensor utilizes thermistor-sensing elements in a low-cost package. Aquasense temperature probe To install Spectrum’s AquaSense, simply drill a 1/4" hole into the PVC piping, insert the probe, then use a standard 1/2" wide hose clamp to seal the O-ring onto the pipe. The molded plastic housing is always in direct contact with the water flow to ensure a fast, accurate temperature reading that is not possible with external sensors. The AquaSense sensor comes standard with 10 feet of AWG#22 PVC jacketed cable with the O-ring installed and ready for use and can easily be adapted for use with RTDs and other temperature sensing technologies. This sensor is available in a variety of RvT curves, thermistor resistance values ranging from 5,000Ω to 30,000Ω and an operating temperature range of –20° C to +100° C. This temperature sensor offers a standard resistance tolerance of ±2% at 25°C. Spectrum’s AquaSense water temperature sensor options include various cable lengths and styles, multiple connectors & terminations and a variety of sensor values & accuracies. Additionally, this sensor is available with a stainless steel housing for potable water environments. These sensors are priced at approx. $ 5.00 @ 10,000 pcs with a lead-time of 4-6 weeks ARO.
