SPT21W Level Transmitter
Features
·Integrated construction, unnecessary to do outer adjustment
·Sensor housing protection IP68
·Cost-efficient, high reliability and stability;
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 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.
