Two new hydrogen sulfide (H2S) gas detection transmitters have been added to OleumTech’s roster. One to its OTC wireless sensor network platform and the other to its H Series hardwired process instrumentation product line. The transmitters offer an H2S measurement range of 0 to 100 ppm with a resolution of 0.1 ppm. The transmitters are equipped with a replaceable sensor module enclosed in a 316 stainless steel housing with a steel mesh filter. The H2S transmitters offer two configurable alarm setpoints: the hardwired RS485 Modbus version is equipped with two solid-state relay outputs as a standard, while the relay outputs are optional on the wireless version; and the OleumTech hydrogen sulfide transmitters are intrinsically safe and certified for use in Class I, Division 1 hazardous locations. The wireless options—WT-H2S and WT-H2S-A—are powered using a replaceable battery pack while the hardwired version, HW-H2S, is powered via a 9-30V DC supply.
