The Berthold UniProbe LB 490 (Part Number: 38477-190) is an advanced level evaluation unit designed for demanding industrial environments. It features a 2000mm plastic scintillator and operates on a power supply of 95 to 250 V (50 - 60 Hz). Housed in a durable stainless steel enclosure with NEMA 4X and IP 66 protection, this unit functions within an ambient temperature range of -40 to +50 degrees Celsius. The system offers menu-controlled calibration via a HART-communicator, automatic decay compensation, and error indication. For connectivity and control, the 38477-190 includes one isolated 0/4 - 20 mA analog output (switchable between passive and active), one digital input for a hold signal, three configurable signal relays, and one dedicated failure relay. It is equipped with four radial 3/4" NPT conduits and holds rigorous certifications including ATEX flame proof protection and FM/CSA classifications for hazardous locations.
