Low Cost Oil / Winding Temperature Indicator

DIRECT MOUNTING TYPE :

1. Steel Direct Vertical Mounting type Oil/Winding Temperature Indicator/Controllers

Model No. : 1017

Steel direct vertical mounting type oil temperature indicator (OTI)/ winding temperature indicators (WTI)

“Osmadial / Sciecon” Mercury in Steel Direct Vertical Mounting type Oil/Winding Temperature Indicator/Controllers are designed to protect the Electrical Power Transformers, Distribution Transformers, Rectifier Transformers from the danger of overheating of the Oil or Winding that would result overloading.

This Instrument is designed to measure the Temperature of Oil/Winding by mounting it directly over the transformer tank in the marshalling box. It is also known as Rigid Stem type Temperature Gauge.

Bulb/Stem : AISI SS 316 Material, SS Bulb 12.5mm OD x 202mm Total Length
Connection : AISI SS 316, 1/2” BSP(M) connection fixed at 154mm from bottom of the bulb.
Contacts : 2 Nos. (1 N.O. + 1 N.C) type Potential Free, Independently adjustable Electro-Mechanical Magnetic snap action type contacts for Alarm & Tripping mechanism
Contact Rating : 230 V AC 125mA / Dc 40 mA
Contact Cable :

1 mtr long 4 core cable at side entry of the case through cable gland.

Zero Adjust : Provided with External Zero Adjustment.

ADVANTAGE OVER OTHER INDICATOR :
This Instrument can be installed directly on transformer tank open to atmosphere without marshalling box.

CAPILLARY TYPE :

1. Capillary type Oil/Winding Temperature Indicator/Controller

Model No. : 1135 / 3A - 4W

capillary type oil temperature indicator (OTI)/ winding temperature indicators (WTI)

“Osmadial / Sciecon” Distance Capillary type Oil/Winding Temperature Indicator/Controller is specially designed for use where the hight of the Transformers is very high.

This instrument incorporates a Capillary between the Case & the Sensor Probe, this helps in mounting the Oil/Winding Temperature Gauge inisde the marshalling box at lower height by extending the Sensor Probe with the help of Capillary tube upto the top of transformer tank, thereby giving the perfect visibility of the temperatures inside the box.


Case : Heavy duty die cast aluminium stoved enamelled Black finished IP-55 weather proof Surface Mounting case.
Dial Size : 100mm Ø, 150mm Ø
Range : 0 - 120°C or as required.
Capillary : 3/5/7 mtr long or as required, fine bore steel capillary covered on with solid drawn Red Duralleum-Teflon capillary, flexible at bottom entry of the case.
Bulb/Stem : AISI SS 316 Material, SS Bulb 10mm OD x 100mm Long
Connection : AISI SS 316, 1/2” BSP(M) connection fixed at 140mm from bottom of the bulb.
Contacts Type* : Ref - A - 4W
2 Nos. (1 N.O. + 1 N.C) type Potential Free, Independently adjustable Electro-Mechanical Magnetic snap action type contacts for Alarm & Tripping mechanism
Contact Rating : 230 V AC 125mA / Dc 40 mA
Contact Cable : 1 mtr long 4 core cable at side entry of the case through cable gland.
