HiTECH’s low-cost, GP-2000 GOOP-PROOF™ radio frequency (RF) point level switch, designated the Model GP-2000, operates on a wide range of liquids, slurries and solid materials. Its Goop-Proof circuit design allows the GP-2000 to Ignore goopy build-up of any type on the sensing probe. Operating on the RF Impedance sensing principle, HiTECH’s GP-2000 will detect the presence (high level) or absence (low level) of virtually any material in any type of bin or tank. It may be made Fail-Safe In either high or low mode. The GP-2000 will operate In conjunction with process materials which range from low dielectric products such as refined oils to conductive slurries. The GP-2000 is used in conjunction with a HiTECH GOOP-PROOF™ sensing probe. They are typically constructed from Teflon and 316 Stainless Steel and can function with high temperatures and pressures as well as being compatible with corrosive process materials.
