NIVELCO Basics // 04 – Various Level and Temperature Transmitters

Описание: NIVOPRESS D hydrostatic level and pressure transmitters operate in 2-wire systems and convert relative or absolute pressure (input signal) into 4…20 mA (output signal). The sensor is protected by a Stainless Steel flush diaphragm, which transfers the pressure to the piezoresistive sensor via silicon oil. Intelligent electronics provide on-site programming with SAP-200 plug-in display or remote programming with HART® communication. Intrinsic safety (Ex ia approved) models are available for use in hazardous environments.

NIVOPRESS N hydrostatic level transmitters are designed to measure the level of clean and contaminated liquids. A sewage adapter operating on the diving bell principle can be snapped into the protecting cap's place to avoid direct contact between the sensor and the measured contaminated liquid. N-500 devices can be used in hazardous environments. The NB/NG plastic housing types are designed for those applications where aggressive mediums (e. g. saline solutions or seawater) may affect even stainless steel.

NIVOFLIP is a bypass level indicator for pressurized vessels with up to 5.5 m flange distance, containing liquids. The device is PED (Pressure Equipment Directive) approved, so it can be used in pressurized vessels up to 100 bar pressure. NIVOFLIP can be equipped with optional limit switches or with NIVELCO’s NIVOTRACK high-precision magnetostrictive level transmitters if the level transmission is necessary. High-temperature versions can withstand up to +250°C.

THERMOPOINT 2-wire temperature transmitters are suitable for continuous multi-point temperature measurement, indication, and transmission of ordinary and hazardous liquids, powders, and granular solids. The 2-wire, loop-operated transmitter head communicates through HART® protocol with control room devices such as a MultiCONT or a PC for data processing and logging.
