SI-100D is a combustible (LNG/LPG) gas leak detector that consists of a sensing unit andreceiver. This is used to detect gas leaks in the pipe or valve. SI-100D can be used withpresent any indicators and PLC using analog output (4-20mA). SI-100D is a low-pricedcompact and light entry-level product.
The smallest and lowest-cost methane and propane gas detector.A suitable gas leak detector for LNG/LPG is the Senko SI-100D. Its catalytic sensor offers precise measurement of 0-100% LEL flammable gases. Explosion-proof, very compact in size, and 4 to 20 mA analogue output make the SI-100D the ideal option for areas where cost-effective investment for simple gas safety monitoring is required.
