Analytical Products ph & ORP Sensors Pre-amplified output. Unlike non-amplified sensors, the preamplifier ensures the process signal is resistant to electrical noise and allows up to 400 feet before connection to instrument. Longer reference path and larger reference volume means longer service life between electrode changes. Flat glass surface sensor design. Resistant to fouling and abrasion in dirty applications, and prevents accidental damage to extend electrode life span. Unique twist-lock design enable ph and temperature connections instantly. Conductivity, Resistivity and Salinity Sensors Flow-through design. Ensures continuous measurement without air entrapment. Reversible threaded connections for in-line or tank usage. Standard parts offer application flexibility for the user. Every sensor uses standard electrical cable. No need to incur additional costs for patch type cable connections. NIST calibration certificate available upon request. Chosen if the specification calls for traceability. Temperature Sensors Unibody and PVDF construction for aggressive fluid conditions. 3/4 in. NPT for easy installation. Pressure Sensors 3/4 in. NPT for easy installation. Pressure ranges to cover a wide range of applications. Chemically inert materials. Instrumentation ProcessPro Transmitters Separate field mount and panel versions. Professionally finished product to suit application specific needs. Multifunctional single input/output or dual input/output available. Large buttons and user friendly features. Dedicated temperature and pressure transmitter added to the family. Scratch resistant/self-healing display window. ProPoint Monitors Dual display one analog, one digital. Indication is seen from a distance combined with accurate digital readings of process parameters. Choice of 6 slide-in dials. Re-calibration is easily achieved in the field without the need for purchasing additional parts. Variety of power requirements. Sensor power, battery power, or AC/DC power versions available makes the ProPoint series usable in almost any application. Intelek-Pro Controllers Instrument modularity. Plug-in input and output cards allow the instrument to be tailored to suit the exact customized needs of the application. 110 VAC/24 VDC power options in one unit. One unit accepts either or both power supplies used for backup power. 15 www.gfsignet.com 15.3

Level Technologies: Simple Guidelines Applications for level measurement are as diverse as any other process parameter, if not more so. This diversity has resulted in the emergence of many different technologies, each offering specific advantages such as non-contacting installation, no moving parts, or accuracy and resolution. + GF + SIGNET s level offering was carefully developed to meet the majority of the most demanding applications. Ultrasonic Point Level Sensors are level switches with no moving parts, used individually or in pairs for multi-point level control. Magnetostrictive (Float) Level Sensors operate on the simple and reliable principle of buoyancy and are unrivaled in accuracy and resolution. Pressure Sensors contain no moving parts and are widely used for level measurement because of their inherent reliability. Ultrasonic Continuous Level Sensors mount above the fluid surface and have no moving parts. This attractive tech-nology is growing in popularity and use, and is ideal for many harsh environments. These sensor types plus other common technologies appear in the chart below, along with some basic considerations for proper selection.
