Pulscon LTC50 HART Mounting Mounting Mounting requirements 6.1.1 Suitable mounting position Figure 6.1 Mounting requirements Mounting distances • Distance (A) between wall and rod or rope probe: • for smooth metallic walls: > 50 mm (2 in) • for plastic walls: > 300 mm (12 in) to metallic parts outside the vessel •...
Page 21 Pulscon LTC50 HART Mounting Additional conditions • When mounting in the open, a weather protection cover (1) may be installed to protect the device against extreme weather conditions. • In metallic vessels: Preferably do not mount the probe in the center of the vessel (2), as this would lead to increased interference echoes.
Page 22 Pulscon LTC50 HART Mounting 6.1.2 Applications with restricted mounting space Mounting with remote sensor The device version with a remote sensor is suited for applications with restricted mounting space. In this case the electronics housing is mounted at a separate position from which it is easier accessible.

Page 30 Pulscon LTC50 HART Mounting Installation at an angle α Figure 6.11 • For mechanical reasons, the probe should be installed as vertically as possible. • With inclined installations the probe length has to be adjusted in dependence to the installation angle.
Page 31 Pulscon LTC50 HART Mounting Plastic or glass tanks: mounting the probe externally at the wall For plastic and glass tanks, the probe can also be mounted on the outside wall under specific conditions. Figure 6.13 Plastic or glass tank Metal sheet with threaded sleeve...
Page 32 Pulscon LTC50 HART Mounting Compensation with the gas phase compensation factor The effect of the dielectric wall can be compared to the effect of a dielectric gas phase. Thus it can be compensated for in the same manner. The compensation factor if given by the quotient of the actual probe length LN and the probe length measured when the tank is empty.
Page 33 Pulscon LTC50 HART Mounting Vessels with heat insulation Note! If process temperatures are high, the device must be included in normal tank insulation to prevent the electronics heating up as a result of heat radiation or convection. The insulation may not exceed beyond the points labeled "MAX" in the drawings.
