Twilight switch  Pune-based Jayashree Electron has recently introduced a reliable and robust automatic ambient light intensity detector switch.  The unit incorporates a twin sensor technology to avoid false or nuisance sensing. The unit is useful for automatic switching “on” loads such as street lights, landscape lights, signboards, monuments, heritage buildings and public places.
Models are also available with built-in programmable timer to switch ‘off’ the loads after preset time or to switch ‘on/off’ loads only in the evening.The unit can operate single phase/three phase loads up to 15 A rating. The unit is housed in IP-65 grade ABS plastic enclosure. The operating light level can be set from 2 lux to 100 lux.
Ultrasonic level sensors(Series RM 3131J)The Ultrasonic level sensors Series SW 3051 are very useful for sensing levels (up to 20 metres.) of liquids and slurry material. The sensor gives 4-20 mA output proportionate to level to the controller unit.
