text: Oldham (France), an Industrial Scientific company , introduces the OLCT 200 gas detection transmitter. The OLCT 200 fixed transmitter is intended for use in monitoring for hazardous levels of industrial gases.
  The OLCT 200 is designed for use with multiple gas detection technologies including electro-chemical, catalytic bead, infrared (IR), and photoionisation detection (PID) sensors. This allows the OLCT 200 to detect many typical gases and provides users the ability to standardise on one transmitter for all of their gas detection needs. Moreover, the OLCT 200 provides users the ability to monitor two different gases simultaneously and further provides the ability to remote mount sensors away from the transmitter and display. This is ideally suited for applications where gas monitoring is needed in remote or difficult to reach locations.
  The OLCT 200 is designed for application flexibility and is compatible with nearly any fixed gas detection installation. It can be configured for 2-wire and 3-wire 4-20mA analog output, Modbus RTU digital output, HART communication and wireless communication. Furthermore, the OLCT 200 offers optional on-board programmable relays and can be configured with either a painted aluminum or stainless steel explosion-proof housing. Additionally, the OLCT 200 can be configured with a cold climate heater to allow for operation in environments where other transmitters cannot effectively perform.
  The OLCT 200â€™s wireless capability provides customers the benefit of a completely wireless gas detection system. The self-contained transmitter provides onboard battery power and wireless data transmission for most of the OLCT 200â€™s gas sensors. Furthermore, the OLCT 200â€™s 900MHz or 2.4GHz wireless communication is directly compatible with all of Oldhamâ€™s WX series alarm controllers and with Oldhamâ€™s MPSIV mobile monitoring system.
  OLCT 200 configurations can be used in explosion-proof and intrinsically safe applications and it has been approved for use in hazardous locations by CSA. Furthermore, the OLCT 200 hardware has been analysed by exida LLC to be suitable for use in SIL 2 applications providing evidence of the OLCT 200â€™s high reliability.
