Introduction
SPT21W is full sealed submersible level transmitter. It is made by building in high stable and reliable OEM piezo-resistive pressure sensor and high accurate circuit board into the stainless steel housing. Integrated construction and standard signal provide the user easy and convenient application in the local working place. The special cable connects with housing, can be immerged into the media for a long time.
SPT21W level transmitter has compact size, light weight and good stability; it can be used for water or liquid measure and control of medicine, metallurgy, electricity, mine, city water supply and drainage and hydrology, etc.

Order Guide
Order Note:
- Please pay attention that the medium should be compatible with the contacted parts; please inform the density of the media (except water);
- Two kinds of cable are optional, polyurethane and polyethylene. The default is polyethylene. Polyurethane cable is more flexible and endurable; it can be selected due to the requirement;
- When the product is used in thunder storm area, we suggest the user to use protection device to protect the product and power grounding reliably;
- For special requirement, please feel free to contact us.
