LMK 358H Detachable Stainless Steel Probe with HART®-Communication Ceramic Sensor accuracy according to IEC 60770: 0.1 % FSO Nominal pressure The detachable stainless steel probe LMK 358H has been designed for level measurement in waste water, waste and higher viscosity media. Basic element is a capacitive ceramic sensor. In order to facilitate stock-keeping and maintenance the sensor head is plugged to the cable assembly with a connector and can be changed easily. 2-wire: 4 ... 20 mA others on request Special characteristics ► HART® communication (setting of offset, span and damping) high overpressure resistance high long-term stability Preferred areas of use are Water ground water level measurement rain spillway basin Sewage waste water treatment water recycling IS-version Ex ia = intrinsically safe for gas and dust accessories e.g. mounting flange with cable gland and terminal clamp BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein Fuel and oil level monitoring in open tanks with low filling heights fuel storage tank farms biogas plants
