Action aims to demonstrate company’s consideration of long term
Sierra Instruments announced it will offer a two-year warranty for its entire line of Innova-Switch flow level switches.
“We’re committed to the highest quality in all our products, and I think this action proves that we’re thinking ahead for our customers’ long-term benefit,” said Scott Rouse, Sierra product manager.
Sierra’s Innova-Switch has been a solid performer in the market for decades, the company said. Designed to meet a broad range of performance and environmental application requirements, the sensor and other wetted materials are 316L stainless steel and feature all welded construction with no moving parts. The Innova-Switch is also easy to install and adjust, giving reliable, low-maintenance performance in the most demanding applications, promises Sierra.
Flow and level detection is accomplished by using a high-resolution thermal differential technique. The sensor consists of a pair of matched resistance temperature detectors (RTDs). One RTD is self-heated using a constant DC current. The other RTD is unheated and provides an accurate process temperature reference. The thermal differential created between the reference and the heated RTD pair is a function of the density and/or velocity of the gas/fluid in contact with the sensor.
The Innova-Switch features an operating temperature range of -100°F to 850°F (-70°C to 458°C) and a range of 0.01- to 5-ft-per-second (fps) liquids and 0.1- to 500-fps gases. The level sensitivity is 0.03 in. The meter features an adjustable response time of 0.5 to 10 seconds (media dependent). Innova-Switch is also CE and CSA approved.
