Product catalog summary

Overview: The LMP 307i is a stainless steel probe designed for continuous level measurement in water and clean or lightly polluted fluids. It features high accuracy and long-term stability, making it suitable for various applications including water systems, groundwater measurement, and fuel storage.

Specifications: The probe offers a nominal pressure range from 0 to 200 mH2O with an accuracy of 0.1% FSO according to IEC 60770. It supports 2-wire (4-20 mA) and 3-wire (0-10 V) output signals. The device is available in optional versions including intrinsically safe (IS) for gas and dust, and with a drinking water certificate.

Technical Data: The probe's input pressure range varies from 0.4 to 20 bar, with overpressure and burst pressure ratings provided. It operates within a temperature range of -10 to 70°C for the medium and -25 to 70°C for storage. The probe is protected against electromagnetic interference and reverse polarity.

Materials and Construction: The housing and diaphragm are made from stainless steel, with various cable sheath options including PVC, PUR, FEP, and TPE-U. The probe is IP68 rated for ingress protection.

Explosion Protection: The LMP 307i is approved for use in explosive environments with specific ATEX and IECEx certifications. It can operate in zones 0 and 20 with defined safety technical maximum values.

Accessories and Options: The document lists various accessories such as mounting flanges, terminal clamps, and display programs. It also provides ordering codes for different configurations and materials.

Applications: The probe is ideal for use in water treatment plants, pump stations, rain spillway basins, and fuel tank farms, among others.
