Product details


. Product Introduction

The TK-603 neutron criticality alarm instrument is a neutron criticality alarm device developed by Beijing Tai Kun Industrial Equipment Co.,Ltd. The instrument uses 3He neutron tubes from American LND company as the probe detectors, with polyethylene as moderator and boric material as energy compensation material which enables the neutron probes to have good energy response to from thermal neutrons to fast neutrons. The criticality alarm instrument has three detection probes.Under the criticality alarm mode, only when more than two of the three probes reach the alarm state, the critical value is considered to be reached, so it has higher detection confidence level than traditional two-probe design. The probes communicate over RS485 links, with the maximum transmission distance up to 1.2km. The host computer is equipped with RS485 and RJ45 communication interface, able to conduct network measurement when combined with upper computer software of our company.

. Main Features

l  The three-probe design widens the detectable range of the device, and each probe adopts 3He tubes as the measurement unit.

l  The alarm setpoint is adjustable.

l  Users can choose real-time dose mode or accumulative dose mode, and can query the data in real time.

l  The host computer has sound and light alarm, and state indicator. Users can know about the operation state of the host computer and whether the environment dose has reached the critical point via corresponding indicators.

l  The host computer has the administrator mode, in order to help users to protect system operations which require higher privileges.
