ME995-3K : VARIABLE DOSERATE KILOGRAMS OF CEMENT PRESET CONTROLLER
The ME995-3K and ME995-3KH VARIABLE DOSERATE preset batch controllers, with new added features complying with Quality Assurance requirements for the concrete additives industry. The controllers incorporate as standard a preact (overflow deduct) feature and a contact drive LED indicator. The most significant new feature is the preact function which compensates for excessive overflows, ideal in speed batching operations and in many cases elimates the need for solenoid valves. With the ME995 batch controllers using the same 10-pin Weidmuller recepticle plug as the previous models, changeover and replacement is instant with no rewiring necessary. Interfacing with PLCs is an easy proceedure (with optional interface fitted), to incorporate safety features and to provide a backup batch facility.
The ME995-3K is a ratio blending controller which calculates and dispenses selected ratios for the batch operator. The top two selectors are for dosage selection of liquid admixture content, marked DOSAGE MLS x 10 / 100 KG. A maximum doserate of 99 x 10 MLS / 100 KGs of cement is selectable. The bottom four selectors are used for selection of cement content per truck load. A maximum of 9000 KILOGRAMS OF CEMENT load is selectable in minimum increments of 10. The display counts upwards in 10 kg lots, dispensing the fluid at the selected doserate up to the target of batch quantity of kilograms of cement selected.
A batch example would be:
- Selected dosage rate 25 x 10ml/100 KG.
- Selected cement content 1500 KILOGRAMS OF CEMENT
- Actual admixture volume received 250 mls x 15*(100 kg) = 3750 millilitres.
- Final batch complete display reading 1500 kgs
The ME995-3KH model calculates and dispenses in the same way, except a higher doserate is selectable via the extra doserate selector knob fitted. A maximum of 900 x10mls/100 KGs can be selected. The controller operates from standard 220 – 260 vac (or optional 110 vac or 12 – 24 VDC) voltage supplies (this must be specified when ordering). Contact output drive is via one, or optional two, relays. Standard controllers are in panel mount format or can be optionally housed in a metal housing box or IP65 ABS wall mount enclosure.
