KS Head mounting PT100 Temperature Transmitter

This economical loop powered PT100 KS head mount temperature transmitter for two and three wire sensors is designed and manufactured in South Africa.    

The extended low voltage operating range allows for use with 12V DC as well as the usual 24V DC sources and makes use of a constant current input circuit to improve accuracy.    

The design is totally analogue, no programming required. Trimming and re-calibration requires no special tools or software. Zero and Span trimmers provide a fine user adjustment.

The red LED indicates that the device is active. The brightness of the LED changes with temperature and indicates that the device is functioning correctly.    

The device has a rugged design and the electronics are encapsulated in resin for added protection.  It operates over a wide temperature range and has excellent RFI immunity.
