PCM261 Level Transmitter for Water Tank and Oil Can

Product overview  PCM261 Level Transmitter accurately measures static pressure of the liquid proportional to the level depth using high performance piezoresistive silicon chip as the measuring element. The result is converted to standard current or voltage signal output through signal conditioning circuit, establishing the linear corresponding relation between the output signal and liquid depth to complete the measurement of the liquid depth. The flange can be customized and the cable is packaged in the armored stainless steel pipe.

Installation in moving water (rivers, lakes, etc.)Installation tips:1) When measuring the water level in flowing water, when the medium fluctuates greatly, a steel pipe can be inserted in the water channel with an inner diameter of about 50 cm. Make several holes of about Φ5 in diameter on the side of the immersed pipe opposite to the flow direction to allow water to enter the pipe and fix the cable and junction box at the outlet of the pipe.2) When the medium of the water channel fluctuates greatly or the sediment is large, a damping device can be installed to filter the sediment, eliminate the adverse effects of dynamic pressure and wave and ensure the measurement accuracy.3) When installing the product in lightening intensified area, please indicate "Lightning Protection" when placing an order. Meanwhile, it is recommended that users install lightning protection devices at the site and ensure that the product and power supply are reliably grounded to reduce damage to the transmitter caused by lightning.  Pressure range selection Pressure range codePressure referencePressure rangeOverpressureBurst pressureRemark0.5miG0.5m H2O300%FS600%FS 1miG1m H2O300%FS600%FS 1.5miG1.5m H2O300%FS600%FS 2miG2m H2O300%FS600%FS 2.5miG2.5m H2O300%FS600%FS 3miG3m H2O300%FS600%FS 3.5miG3.5m H2O300%FS600%FS 4miG4m H2O300%FS600%FS 4.5miG4.5m H2O300%FS600%FS 5miG5m H2O300%FS600%FS 5.5miG5.5m H2O300%FS600%FS 6miG6m H2O300%FS600%FS 6.5miG6.5m H2O300%FS600%FS 7miG7m H2O300%FS600%FS 8miG8m H2O300%FS600%FS 9miG9m H2O300%FS600%FS 10miG10m H2O200%FS500%FS 12miG12m H2O200%FS500%FS 15miG15m H2O200%FS500%FS 18miG18m H2O200%FS500%FS 20miG20m H2O200%FS500%FS   Cable length selection Pressure range codeMapping relationCodeDefinition0.5miL1.5 L2 L3 L5 L6 L8 L10 L12 L15 L18 L20 L25L1.5Cable length 1.5m1miL1.5 L2 L3 L5 L6 L8 L10 L12 L15 L18 L20 L25L2Cable length 2m1.5miL2 L3 L5 L6 L8 L10 L12 L15 L18 L20 L25L3Cable length 3m2miL3 L5 L6 L8 L10 L12 L15 L18 L20 L25L5Cable length 5m2.5miL3 L5 L6 L8 L10 L12 L15 L18 L20 L25L6Cable length 6m3miL5 L6 L8 L10 L12 L15 L18 L20 L25L8Cable length 8m3.5mi
