Tek-Trol Pressure Sensors-Transmitters
Tek-Trol pressure sensors and transmitters are designed for high-accuracy, real-time monitoring of pressure in industrial environments. Their presence is felt wherever precision and reliability rule the day. They convert pressure into steady electrical signals that are fed directly into control systems—signals that modern automation can use to monitor anything from pumps to process vessels in core oil and gas, chemical processing, water treatment, and manufacturing applications.
What sets Tek-Trol pressure transmitters apart is the stunning variety of sensing technologies, materials, and pressure ranges they manufacture. These include differential, gauge, absolute, and multi-range transmitters designed for both (low-pressure) air systems and (high-pressure) industrial fluids. Many of their models serve standard output signals like the 4–20 mA current loop, HART, Modbus, and other digital communication protocols. Yet, Tek-Trol still delivers the kind of flexibility that makes engineers and system integrators love them. If you need a pressure transmitter for a legacy system, a digital system, or both, Tek-Trol makes it work in either scenario.
FAQs
What industries use Tek-Trol pressure sensors and transmitters?
Tek-Trol devices are widely used in water/wastewater, oil and gas, chemical processing, food and beverage, and general industrial automation applications.
What is the accuracy of Tek-Trol pressure transmitters?
Most Tek-Trol transmitters offer high-accuracy performance within ±0.1% to ±0.25% of full scale, depending on the model and application.
Are Tek-Trol pressure sensors compatible with harsh or hazardous environments?
Yes, many Tek-Trol models feature rugged housings, sealed electronics, and certifications suitable for corrosive, high-vibration, and hazardous locations.
What communication outputs do Tek-Trol pressure transmitters offer?
Common outputs include 4–20 mA, HART, Modbus, and other digital protocols to integrate with PLCs, SCADA systems, and industrial control networks.
How do I select the right Tek-Trol pressure sensor for my application?
Consider pressure range, media compatibility, temperature, accuracy requirements, process connection, and the control system you are integrating with.
Instrumentation: Elements & Transmitters
2 pieces of hardware used in modern day instrumentation: measuring elements and transmitters.
Measuring Elements
Measuring elements are the part of the device that performs the measurement. For example, the measuring element of a pressure transducer is the part that is actually lowered into a tank that will take a pressure measurement. The measuring element of a flow meter is the part that actually measures the flow and an RTD or thermocouple takes the temperature measurement.
Transmitters
Transmitters collect information from measuring elements and sends the information to where it is needed. The transmitter interfaces with the measuring element and interprets the information. It then sends that information to a PLC, RTU or some other type of control unit. In many cases, the transmitter has the ability to communicate the information via multiple communication protocols. This may be necessary when the measuring element does not send the same type of signal that is needed by the controller. For example, it may be necessary to convert a temperature reading from a thermocouple to a 420 milliamp signal that can be received by a local PLC.
