Thermistor Temperature Sensors

Thermistor Temperature Sensors

Dwyer Instruments, Inc. manufactures and offers many temperature measuring products that use a thermistor as the sensing element.

Thermistors are based on the principal that the electrical resistance of semiconductor materials is a function of the temperature. Thermistors work well over smaller temperature ranges with better accuracy than  (RTD) but are very non-linear. They also generally offer better response times. Thermistors have much higher resistance values than RTDs, with ranges typically ranging from 100 ohms to 100 megaohms.

The Importance of Regulatory Compliance in a Manufacturing Setting

There are numerous factors that lead to regulatory compliance, including: reputation, image, ethics, competition, and survival. Regulatory is often looked at as the “show-stopper” or obstacle in many manufacturing processes. While regulatory may sometimes be perceived as negative, it can also be the main key to a company’s success. Continue reading “The Importance of Regulatory Compliance in a Manufacturing Setting”

The Intricacy of Proper Instrumentation in Cleaning Produced Water

The cleaning of produced water during oil and gas production and exploration is a crucial, although costly endeavor. In the process of bringing oil and gas up to the surface from a well, several byproducts are also produced. Water is the largest of these byproducts by volume, with 882 billion gallons produced per day. This produced water contains a variety of other compounds and substances, including organic and inorganic compounds, grease, bacteria, and dissolved solids such as iron.

Flow Technologies: Out With the Old, In With the New

As technology advances and new ways to solve old problems are discovered, consumers are left to decide whether existing technology suffices for their specific needs or if they need to pursue new, higher cost technology alternatives. This is very much the case when considering flow instrumentation where moving parts, such as turbines and paddles, are being replaced with non-moving part technologies, such as: ultrasonic, thermal, or electromagnetic sensors. But how do you decide which of these products to select for your flow application? Below is a list of items to take into consideration when deciding between mechanical or non-mechanical technology flowmeters. Continue reading “Flow Technologies: Out With the Old, In With the New”
