好消息，西门子旋转阻尼式物位开关，最新型号LPS200，属于高温型，可以应用到220摄氏度的高温情况下。

所以，风------，你可以跟西门子的销售人员联系。可能还有部分销售人员没有看到最新产品型号，可以告诉让其在内部网站上查找。

SITRANS LPS200 paddle switch and LVS200 vibrating level switch now offer high temperature, high
pressure, and interface models. These switches, previously sold as the Milltronics Pointek PLS 200 and
VLS 200, provide low cost, reliable high and low level alarms for a wide variety of bulk solid applications.
Based on a proven product design, these switches are exceptionally durable, with special features
including a dual bearing seal on the paddle switch that protects the mechanism from dust and moisture.
They are easy to set up and can be readily connected to an alarm or control system. The unique friction
clutch mechanism prevents damage by falling materials and avoids gear failure.
The new high temperature version of SITRANS LPS200, the rotating paddle switch, is effective up to
220 °C (428 °F) and the new high pressure version performs in environments up to 10 bar (145 psi).
SITRANS LPS200 detects full, empty, or demand conditions in materials including grain, animal feed,
cement, plastic granules, and wood chips. The standard measuring vane is effective in materials with
densities as low as 100 g/l (6.25 lb/ft³). SITRANS LPS200 can be configured with a hinged vane for
increased sensitivity to materials with densities as low as 35 g/l (2.19 lb/ft³). The paddle sensitivity can be
adjusted for varying material properties. Configurations available include a compact version, rigid
extended, or cable version up to 10 meters (32 ft).
SITRANS LVS200 is a vibrating level switch that detects the absence or presence of dry bulk solids with
densities as low as 20 g/l (1.3 lb/ft³). A new interface version that detects solids in liquids and is effective
in high load applications is now also available. A pipe extension kit of up to 4 meters (14 ft), with customer
supplied pipe, has been added to the product line, allowing the electronics to be separated from the
process. Fork oscillation constantly cleans the tines, and the unique patented design of the fork-andcrystal
assembly eliminates false high-level readings. SITRANS LVS200 has a compact design and can
be top or side-mounted.
