Knick Interface, LLC is a North American subsidiary of the Berlin-based Knick Elektronische Messgeräte. Focussing on quality above all else, Knick Interface manufactures a broad range of electrical interface products including universal signal conditioners for measuring DC voltages and currents with galvanic isolation, transmitters for temperature and AC signals, active and passive isolators for standard signals, transducers for high voltages and shunt applications, and repeater power supplies for 2-wire sensors. A majority of these devices offer selectable calibrated input ranges with flexible output options that allow these products to be used for a broad range of applications, resulting in reduced inventory costs for businesses and simplified operation for end users. Founded by Engineer Ulrich Knick from Berlin, Germany more than 70 years ago, Knick Interface is dedicated to providing innovative enterprise measuring and monitoring devices for factory automation and process control industries while still upholding the family company traditions that made them initially successful.

Interface Technology

High-precision signal conditioners and transmitters for demanding applications and maximum reliability.

Universal signal conditioners for measuring DC voltages and currents with galvanic isolation, active and passive isolators for standard signals, repeater power supplies for 2-wire sensors, transmitters for temperature and AC signals, transducers for high voltages and shunt applications. Switchable calibrated input ranges and flexibly selectable standard signals on the output allow for a broad range of applications. Inventory costs are reduced and operation is simplified.

The ProLine’s intelligent circuitry minimizes failure rates and achieves MTBF values of up to 1030 years. The high quality is ensured by careful product development, comprehensive design verifications and 100% routine tests. Warranty: 5 years.

International certifications such as UL, CSA, CE, GL, SIL, KTA, ATEX, GOST allow the devices to be used worldwide. This applies particularly to the models with broad-range power supply. Isolators of the ProLine series provide crucial benefits for applications with high demands on isolation, signal transmission speed and long-term stability.

Temperature Transmitters

A temperature transmitter is a device used to transmit signals from a temperature sensor onto a measurement control device like a data logger, display, or recorder by sending a standardized output signal. In manufacturing plants, a common output would range from 4-20mA or 0-10V DC, 4mA representing zero degrees Celsius.

Analog Signal Converters

A universal signal converter is used in situations where temperature, pressure, weight, and speed are measured. An Analog Signal Conditioner will assist the signal and prevent it from fading as it is transmitted to the control room. These devices are typically used in power plants, steel production facilities, water plants, chemical processing plants, and more.

Knick Interface’s products offer a wide range of output options and selectable calibrated input ranges, meaning they can be used in a variety of applications and result in simplified operation and reduced costs.
