Define Instruments launches Sentry trip amplifier

April 2016 Sensors & Transducers

Define Instruments has announced the launch of its new product: the Sentry.

The Sentry is a compact, DIN rail mountable signal conditioner measuring just 23 mm wide. Described as the “Swiss Army knife” of trip amplifiers, its primary use is in monitoring and alarming applications.

The Sentry accepts seven signal input types (potentiometer, V, Tc, mA, Freq, NTC and RTD) and works with either AC or DC voltage (24-250 VAC or 19-250 VDC). This provides in-field flexibility as it can be plugged in to whatever power source is available and eliminates the risk of the unit being accidentally blown up by use of an incorrect power supply.

It has two relay outputs for alarm or control applications and an optional isolated analog output, which converts signals to 0-10 V or 4-20 mA for forwarding to a PLC or scada systems.

A unique and distinguishing feature of the Sentry is its four digit display, a big advantage when it comes to ease of commissioning and fault finding. Additionally, the Sentry supplies the excitation required for common sensors and transmitters.

Configuration takes just 60 seconds using Define’s free ToolBox software. The software includes wiring diagrams and application examples to assist the less technically knowledgeable to program the unit with the minimum of hassle.
