Readings and alarm points are displayed on a digital alphanumeric panel, and data can be output to facility automation systems. The modular design features RJ-45 connectors for rapid installation. NIST-traceable inputs are optional.
Racks are available with removable or nonremovable hangers.
Voltmeter Trek Medina, NY The Model 520 voltmeter is a pocket-sized, handheld tool for measuring electrostatic surface voltages over a wide range of spacings. This capacity enables operators to inspect small spots for charge accumulation. A voltage monitor output for connecting to a recording device is optional. The sensor's ceramic shaft and Rulon-bearing insert for the Teflon miniature rotor wheel give the device a lifespan of about seven years. Features include a flowmeter with an output of 4 to 20 mA, an adjustable flow switch, an LED linked to a relay, and a visual flow indicator.
